Sample Karnataka II PUC Physics (KSEAB) Practice Questions

Try these sample questions to review concepts for the Karnataka II PUC Physics (KSEAB) exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1The electrostatic force between two point charges separated by distance r in vacuum is F. If the distance is doubled and each charge is doubled, the new force is:
A.2F
B.4F
C.F/4
D.F
Explanation: F' = k(2q)(2q)/(2r)² = k(4q²)/(4r²) = kq²/r² = F. The factors cancel, so the force remains F.
2Two charges +4 μC and +9 μC are placed 30 cm apart. The electric field is zero at a point:
A.18 cm from +4 μC toward +9 μC
B.outside the segment, beyond +4 μC
C.10 cm from +4 μC toward +9 μC
D.12 cm from +4 μC toward +9 μC
Explanation: Between like charges, E = 0 divides the segment in the ratio of √|q|. Let x be from +4 μC: k(4×10⁻⁶)/x² = k(9×10⁻⁶)/(0.3−x)² ⇒ 2/x = 3/(0.3−x) ⇒ 2(0.3−x)=3x ⇒ 0.6=5x ⇒ x=0.12 m = 12 cm from +4 μC.
3An electric dipole of moment p is placed in a uniform electric field E with p parallel to E. The torque on the dipole is:
A.pE/2
B.2pE
C.pE
D.zero
Explanation: Torque τ = pE sinθ. When p is parallel to E, θ = 0°, so sinθ = 0 and τ = 0. (Net force is also zero in a uniform field.)
4According to Gauss’s law, the electric flux through a closed surface is:
A.always zero if the surface is spherical
B.independent of the enclosed charge
C.proportional to the average electric field on the surface
D.equal to q_enclosed/ε₀ in SI units
Explanation: Gauss’s law: ∮ E·dA = q_enclosed/ε₀ (SI). Flux depends only on the total charge enclosed, not on surface shape.
5A charge Q is uniformly distributed on a thin spherical shell of radius R. The electric field at distance r from the centre for r < R is:
A.kQ/(R²r)
B.kQ/r²
C.kQ/R²
D.zero
Explanation: For a point inside a uniformly charged thin shell, a Gaussian surface of radius r < R encloses zero charge, so E = 0 (Gauss’s law).
6The electric field due to an infinite plane sheet of charge density σ (SI) has magnitude:
A.σ/(4πε₀)
B.2σ/ε₀
C.σ/ε₀
D.σ/(2ε₀)
Explanation: Using a Gaussian pillbox through an infinite non-conducting sheet (or standard textbook result for a single infinite sheet), E = σ/(2ε₀), independent of distance.
7Two charges +q and +4q are separated by distance d. A third charge Q is to be placed on the line joining them so that the net force on it is zero. Q must be placed:
A.between the charges, closer to +4q
B.outside, beyond +q
C.outside, beyond +4q
D.between the charges, closer to +q
Explanation: For net force zero on Q, the forces from +q and +4q must be equal and opposite, so Q must lie between them (repulsion from both sides). Distance from +q : distance from +4q = √1 : √4 = 1 : 2, so closer to the smaller charge +q.
8An electric dipole of moment 2×10⁻⁶ C·m is placed in a uniform field of 10⁵ N/C with its axis at 60° to the field. The magnitude of torque is:
A.0.2 N·m
B.0.05 N·m
C.0.1 N·m
D.0.173 N·m
Explanation: τ = pE sinθ = (2×10⁻⁶)(1×10⁵)sin60° = 0.2 × (√3/2) = 0.1√3 ≈ 0.173 N·m.
9A charge of 2 μC is placed at the centre of a cube of side 10 cm. The electric flux through one face of the cube is:
A.2×10⁻⁶/(8ε₀)
B.zero
C.2×10⁻⁶/ε₀
D.2×10⁻⁶/(6ε₀)
Explanation: Total flux through the closed cube is q/ε₀ = 2×10⁻⁶/ε₀. By symmetry the flux is equally shared by 6 faces, so flux through one face = (2×10⁻⁶)/(6ε₀).
10The SI unit of electric field intensity is equivalent to:
A.N/C or V/m
B.J/C
C.C/N
D.N·m/C
Explanation: E = F/q so unit is N/C. Also E = −dV/dr so unit is V/m. Both are equivalent.

About the Karnataka II PUC Physics (KSEAB) Exam

Karnataka II PUC Physics is the Class 12 Pre-University public examination physics paper under the Karnataka School Examination and Assessment Board (KSEAB), subject code 33. It assesses NCERT Class 12 Physics (rationalized syllabus as adopted for Karnataka II PUC): electric charges and fields; electrostatic potential and capacitance; current electricity; moving charges and magnetism; magnetism and matter; electromagnetic induction; alternating current; electromagnetic waves; ray optics and optical instruments; wave optics; dual nature of radiation and matter; atoms; nuclei; and semiconductor electronics. The official assessment is commonly ~70 marks theory (mixed objective-style and short/long answers, about 3 hours 15 minutes) plus ~30 marks practical. Fees and exact blueprints are notified by KSEAB / DPUE (kseab.karnataka.gov.in; dpue-exam.karnataka.gov.in). Pass marks are commonly described near ~35% overall with separate theory/practical floors as notified. The 100 questions on this page are a free English-language multiple-choice study adaptation with explanations and multi-step calculation practice; they are not a full simulation of the official mixed theory paper or practical exam.

Exam sponsor: Karnataka School Examination and Assessment Board (KSEAB). The requirements and fees below concern the certification or admission exam, separate from our free practice resources.

Assessment

Official KSEAB II PUC Physics (code 33) is assessed as approximately 70 marks theory and 30 marks practical (total 100).

English and Kannada media are typically available. Exact theory–practical splits and attempt rules are as published for the year — confirm circulars on kseab.karnataka.gov.in and dpue-exam.karnataka.gov.in. This practice bank is an English-language MCQ study adaptation for concept and calculation fluency — it does not simulate official attempt limits, long derivations, or practical examinations.

Karnataka II PUC Physics (KSEAB): Suggested Study Strategy

1Practice official KSEAB/DPUE Physics (code 33) model papers under timed ~3 h 15 m conditions so you can switch from MCQ drills to written 2-, 3-, and 5-mark answers with diagrams.
2For numericals, write the formula first (F = qE, V = IR, 1/v − 1/u = 1/f, ε = −dΦ/dt, λ = h/p), substitute SI units, and show intermediate steps — boards often require detailed solutions.
3Memorize sign conventions for mirrors/lenses and Lenz’s-law direction rules; many lost marks come from sign or induced-current direction errors.
4Build a one-page formula sheet for electrostatics, circuits, magnetism, EMI/AC, optics, and modern physics; revise it weekly before annual exams.
5Do not neglect practicals: experiment technique, graph plotting, and viva concepts contribute ~30 marks.
6Use English/Kannada textbooks as directed by your college; this free bank is an English MCQ adaptation only.
