Q.1 Which of the following is a vector quantity?
(a) Work
(b) Energy
(c) Power
(d) Force
Answer: (d) Force
Explanation:
Work, energy & power are scalars as they only have magnitude. Force has both magnitude and direction, so it is a vector.

(a) [MLT⁻²]
(b) [ML²T⁻¹]
(c) [ML²T⁻²]
(d) [ML²T⁻¹]

Explanation:
Planck’s constant has units of energy × time = (ML²T⁻²) × T = ML²T⁻¹.
Q.3 Which of the following does not represent simple harmonic motion?
(a) Motion of a simple pendulum for small amplitude
(b) Motion of a particle on a spring
(c) Motion of the needle of a sewing machine
(d) Motion of a tuning fork
Answer: (c) Motion of the needle of a sewing machine
Explanation:
Simple harmonic motion (SHM) involves oscillatory motion about a mean position governed by a restoring force ∝ displacement. Sewing machine needle moves up and down, but not in SHM.
Q.4 The acceleration due to gravity on the surface of Earth is 9.8 m/s². What will be its value at the center of Earth?
(a) 9.8 m/s²
(b) Zero
(c) Infinite
(d) 4.9 m/s²
Answer: (b) Zero
Explanation:
At Earth’s center, the gravitational force from all directions cancels out. Hence, g = 0 at the center.
Q.5 Which of the following is the unit of electric field?
(a) Newton
(b) Coulomb
(c) Volt/meter
(d) Ohm
Answer: (c) Volt/meter
Explanation:
Electric field (E) = Force/Charge = N/C = (J/C)/m = V/m.
Q.6 The dimensional formula of impulse is the same as that of:
(a) Force
(b) Momentum
(c) Work
(d) Power
Answer: (b) Momentum
Explanation:
Impulse = Force × time = (MLT⁻² × T) = MLT⁻¹ = Momentum.
Q.7 Find out which of the following statements is correct?
(a) Mass is a vector & weight is a scalar
(b) Mass is a scalar & weight is a vector
(c) Both mass & weight are scalars
(d) Both mass & weight are vectors
Answer: (b) Mass is a scalar & weight is a vector
Explanation:
Mass has magnitude only, hence scalar. Weight is the force of gravity acting on mass and has direction, hence vector.
Q.8 If the velocity of a body is doubled, its kinetic energy becomes:
(a) Unchanged
(b) Double
(c) Four times
(d) Eight times
Answer: (c) Four times
Explanation:
K.E. = ½ mv². If v → 2v, then K.E. = ½ m (2v)² = 4 × original.
Q.9 If a body is moving in a circular path with uniform speed, then:
(a) Acceleration is directed away from center
(b) Velocity is constant
(c) Acceleration is directed towards center
(d) Acceleration is zero
Answer: (c) Acceleration is directed towards center
Explanation:
Centripetal acceleration acts towards the center of the circle in uniform circular motion.

Q.10 Which of the following has the least wavelength?
(a) Infrared rays
(b) X-rays
(c) Microwaves
(d) Radio waves
Answer: (b) X-rays
Explanation:
Radio < Microwaves < Infrared < Visible < X-rays < Gamma (increasing frequency, decreasing wavelength). So X-rays have the least among given.
Q.11 Which of the following is not a thermodynamic process?
(a) Isothermal
(b) Isobaric
(c) Isochoric
(d) Isokinetic
Answer: (d) Isokinetic
Explanation:
Thermodynamic processes are classified as isothermal (T constant), isobaric (P constant), and isochoric (V constant). Isokinetic is not one.
Q.12 The work done in moving a charge of 2 C across two points having a potential difference of 12 V is:
(a) 24 J
(b) 6 J
(c) 12 J
(d) 0 J
Answer: (a) 24 J
Explanation:
Work (W) = q × V = 2 × 12 = 24 J.
Q.13 The relation between pressure (P), volume (V), and temperature (T) is given by:
(a) Boyle’s law
(b) Charles’ law
(c) Gay Lussac’s law
(d) Ideal gas equation
Answer: (d) Ideal gas equation
Explanation:
Ideal gas law: PV = nRT, relating pressure, volume, and temperature together.

Answer: (c) Violet
Explanation:
Deviation ∝ refractive index. Violet has shortest wavelength and highest refractive index, so deviates most.
Q.19 The SI unit of power of a lens is:
(a) Watt
