Sample WBCHSE HS Physics Practice Questions

Try these sample questions to test your WBCHSE HS Physics exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 91+ question experience with AI tutoring.

1A body in linear motion starts with an initial velocity of 10 m/s and uniform acceleration of 2 m/s². What is its velocity after 3 seconds?
A.30 m/s
B.26 m/s
C.11 m/s
D.16 m/s
Explanation: Using the first equation of motion v = u + at, we have v = 10 + (2)(3) = 16 m/s.
2A resistor of 10 Ω has a current of 2.0 A flowing through it. What is the potential difference across the resistor?
A.10.0 V
B.40.0 V
C.25.0 V
D.20.0 V
Explanation: According to Ohm's Law, V = IR. Thus, V = 2.0 A × 10 Ω = 20.0 V.
3A constant force of 50 N acts on an object, displacing it by 4 m in the direction of the force. What is the work done?
A.250 J
B.100.0 J
C.12.5 J
D.200 J
Explanation: Work is calculated as W = F × d × cos(θ). Since the force and displacement are in the same direction, cos(0°) = 1. W = 50 × 4 = 200 J.
4What is the net force required to give a 5.0 kg mass an acceleration of 3 m/s²?
A.0.60 N
B.15.0 N
C.1.67 N
D.25.0 N
Explanation: From Newton's Second Law, F = ma. So, F = 5.0 kg × 3 m/s² = 15.0 N.
5The rest mass energy of a particle with mass 1 mg (milligrams) is approximately:
A.9.0e+10 J
B.9.0e+07 J
C.3.0e+08 J
D.9.0e+13 J
Explanation: Using Einstein's mass-energy equivalence E = mc². 1 mg = 1 × 10^-6 kg. E = (1 × 10^-6) × (3 × 10^8)² = 9.0e+10 J.
6What is the energy of a photon with frequency 4.0e+14 Hz? (h = 6.63 × 10⁻³⁴ J·s, 1 eV = 1.6 × 10⁻¹⁹ J)
A.3.31 eV
B.2.65e-19 eV
C.1.66 eV
D.0.83 eV
Explanation: E = hf. E = (6.63 × 10⁻³⁴) × (4.0e+14) = 2.65e-19 J. Converting to eV: 2.65e-19 / (1.6 × 10⁻¹⁹) = 1.66 eV.
7A projectile is launched with an initial velocity of 20 m/s at an angle of 30° to the horizontal. Assuming g = 9.8 m/s², what is the horizontal range?
A.17.7 m
B.35.3 m
C.40.8 m
D.20.4 m
Explanation: Range R = u² sin(2θ) / g. R = (20)² sin(60°) / 9.8 = 35.3 m.
8Two resistors of 4 Ω and 4 Ω are connected in parallel. This combination is connected in series with a 5 Ω resistor. What is the equivalent resistance?
A.13.0 Ω
B.1.4 Ω
C.2.0 Ω
D.7.0 Ω
Explanation: Parallel combination Rp = (4 × 4)/(4 + 4) = 2.0 Ω. Total resistance = Rp + 5 = 7.0 Ω.
9An object is placed 15 cm in front of a convex lens of focal length 10 cm. What is the image distance?
A.6.0 cm
B.-30.0 cm
C.30.0 cm
D.25.0 cm
Explanation: Lens formula: 1/f = 1/v - 1/u. 1/v = 1/f + 1/u = 1/10 + 1/-15. Solving gives v = 30.0 cm. Positive v indicates a real image on the other side.
10A planet has a mass 2 times that of Earth and a radius 1.5 times that of Earth. If Earth's escape velocity is 11.2 km/s, what is the escape velocity on this planet?
A.33.6 km/s
B.14.9 km/s
C.9.7 km/s
D.12.9 km/s
Explanation: Escape velocity v = √(2GM/R). So, v' = v × √(M'/M) / √(R'/R) = 11.2 × √(2/1.5) = 12.9 km/s.

About the WBCHSE HS Physics Exam

The WBCHSE HS Physics exam evaluates students on core physics principles across classical mechanics, electromagnetism, optics, thermodynamics, and modern physics. It includes theoretical derivations, numerical problems, and conceptual questions. This OpenExamPrep bank is an English-language four-option MCQ study aid for WBCHSE Higher Secondary; it does not replace official Bengali/English board papers, descriptive answers, or required practical/project/performance evidence.

Assessment

WBCHSE Higher Secondary subject PHYS: Semesters I–IV across Classes XI–XII; theory examinations plus practical/project/performance where the syllabus requires them.

Time Limit

As per semester notification (typically 2–3 hours for theory sittings)

Passing Score

30% minimum in theory and in practical/project independently (WBCHSE examination FAQ)

Exam Fee

Semester enrolment fee structure (Council): Sem III/IV student total INR 215 (155 enrolment + 30 processing + 30 convenience), with INR 190 to Council and INR 25 centre grant; supplementary often INR 50/paper.

Frequently Asked Questions

What is the passing marks for WBCHSE HS Physics?

Students must secure at least 30% in theory and in practical/project independently for the mandatory best-of-five subjects (two languages and three electives), per the Council examination FAQ.

Is calculator allowed?

Standard non-programmable calculators are generally not allowed unless specified in the admit card, students must rely on manual calculations for most board exams.

What are the most important chapters?

Optics, Current Electricity, Electrostatics, and Modern Physics typically carry significant weightage.

How are practicals evaluated?

Practicals are evaluated internally and externally based on experiments performed, viva voce, and the practical record book.

Are previous year questions repeated?

Concepts are frequently repeated, and occasionally similar numericals appear, making past papers highly valuable for preparation.

What is the format of the theory paper?

The theory paper consists of multiple-choice questions (MCQs), very short answer questions (VSAQs), short answer questions, and long answer questions.

Are these MCQs identical to the official WBCHSE PHYS question paper?

No. Official non-language elective papers are set in Bengali and English under the semester system and may include descriptive and practical/project components. These items are an English MCQ study adaptation only.
