1Two like point charges repel each other with force F when separated by distance r in vacuum. If the separation is doubled, the repulsive force becomes:
A.F/2
B.2F
C.4F
D.F/4
Explanation: Coulomb's law states F proportional to 1/r squared. Doubling the separation multiplies the force by 1/4, so the new force is F/4. The charges remain like, so the force is still repulsive but weaker.
2Two point charges +3 μC and −2 μC are placed 2 m apart in vacuum. The magnitude of the electrostatic force between them is (k = 9×10^9 N m^2 C^−2):
A.1.35×10^−2 N
B.2.7×10^−2 N
C.6.75×10^−3 N
D.1.35×10^−3 N
Explanation: F = k|q1 q2|/r^2 = (9×10^9)(3×10^−6)(2×10^−6)/(2)^2 = (9×10^9)(6×10^−12)/4 = 54×10^−3/4 = 1.35×10^−2 N. Opposite signs mean attraction, but magnitude is positive.
3Electric field intensity at a point is defined as the electrostatic force experienced by a:
A.unit magnetic pole placed at that point
B.unit positive charge placed at that point
C.unit negative charge placed at that point
D.unit mass placed at that point
Explanation: By definition E = F/q0 for a small positive test charge q0. The direction of E is the direction of force on a positive charge. Unit mass defines gravitational field strength, not electric field.
4The electric field due to a point charge of 2 μC at a distance of 3 m in vacuum is (k = 9×10^9 SI units):
A.2×10^4 N/C
B.9×10^3 N/C
C.2×10^3 N/C
D.6×10^3 N/C
Explanation: E = kq/r^2 = (9×10^9)(2×10^−6)/(3)^2 = 18×10^3/9 = 2×10^3 N/C. Direction is radially outward because the charge is positive.
5Charges +q and +4q are fixed 30 cm apart. A third charge is placed on the line joining them so that the net force on it is zero. Its distance from +q is:
A.20 cm (between the charges)
B.6 cm (between the charges)
C.15 cm (midpoint)
D.10 cm (between the charges)
Explanation: Let the null point be at distance x from +q. Then kqQ/x^2 = k(4q)Q/(0.30−x)^2 gives 1/x = 2/(0.30−x), so 0.30−x = 2x and x = 0.10 m = 10 cm. For like charges the null point lies between them, closer to the smaller charge.
6The SI unit of electric potential is the:
A.volt
B.newton
C.coulomb
D.farad
Explanation: Electric potential V equals work done per unit charge; 1 V = 1 J/C. Newton is force, coulomb is charge, and farad is capacitance.
7Electric potential due to a charge of 5 μC at a distance of 9 m from it in vacuum is (k = 9×10^9):
A.9×10^3 V
B.5×10^3 V
C.4.5×10^4 V
D.5×10^2 V
Explanation: V = kq/r = (9×10^9)(5×10^−6)/9 = 45×10^3/9 = 5×10^3 V. Potential is a scalar and falls as 1/r, not 1/r^2.
8Three identical capacitors each of capacitance C are connected in series. Their equivalent capacitance is:
A.C
B.C/2
C.C/3
D.3C
Explanation: For n equal capacitors in series, 1/Ceq = n/C so Ceq = C/n. With n = 3, Ceq = C/3. Series connection reduces equivalent capacitance below any single capacitor.
9A 2 μF parallel-plate capacitor is charged to 100 V and then disconnected from the battery. If the plate separation is doubled (dielectric still air), the stored energy becomes:
A.5.0×10^−3 J
B.1.0×10^−2 J
C.4.0×10^−2 J
D.2.0×10^−2 J
Explanation: Initially U = (1/2)CV^2 = (1/2)(2×10^−6)(100)^2 = 1.0×10^−2 J. After disconnection Q is constant. Doubling d halves C. With Q fixed, U = Q^2/(2C) doubles to 2.0×10^−2 J. Energy is supplied by the work done in separating the plates against attraction.
10Gauss's law states that the net electric flux through a closed surface is equal to:
A.q_enclosed/ε0
B.q_enclosed × ε0
C.E × A only
D.zero always
Explanation: Gauss's law: closed surface integral of E·dA equals q_encl/ε0 in SI. Flux depends only on the enclosed charge, not on charges outside the Gaussian surface.

About the RBSE SS Physics Exam

RBSE SS Physics: Suggested Study Strategy

1Map every practice session to the official RBSE Physics unit list, not only popular coaching lists.
2After MCQ drills, write full answers from RBSE-style model papers under timed conditions.
3Verify facts (dates, formulas, definitions) against NCERT/RBSE prescribed books before trusting any third-party summary.
4Track weak categories and re-attempt missed items after 48 hours.
5For languages, literature, music, drawing, typewriting, and shorthand, MCQs support theory—still complete official skill practice.
