-
Q1.Which colour of visible light has the longest wavelength?
Show answer & explanation
Answer: C — Red
Red light has the longest wavelength (~700 nm).
-
Q2.A body with initial velocity 17 m/s accelerates at 4 m/s² for 8 s. Find the distance covered.
Show answer & explanation
Answer: A — 264 m
s = ut + ½at² = 17×8 + ½×4×8² = 264 m.
-
Q3.Work done is zero when the force is:
Show answer & explanation
Answer: B — Perpendicular to displacement
W = Fd cos θ; at 90° cos θ = 0.
-
Q4.A body starts at 10 m/s and accelerates uniformly at 1 m/s² for 8 s. Find its final velocity.
Show answer & explanation
Answer: D — 18 m/s
v = u + at = 10 + 1×8 = 18 m/s.
-
Q5.The unit of electrical resistance is the:
Show answer & explanation
Answer: D — Ohm
Resistance is measured in ohms (Ω).
-
Q6.Find the power dissipated when 2 A flows through a 12 Ω resistor.
Show answer & explanation
Answer: B — 48 W
P = I²R = 2² × 12 = 48 W.
-
Q7.The SI unit of force is the:
Show answer & explanation
Answer: C — Newton
1 newton = 1 kg·m/s².
-
Q8.Sound cannot travel through:
Show answer & explanation
Answer: B — Vacuum
Sound needs a medium; it cannot travel through a vacuum.
-
Q9.Find the kinetic energy of a 21 kg body moving at 10 m/s.
Show answer & explanation
Answer: B — 1,050 J
KE = ½mv² = ½ × 21 × 10² = 1,050 J.
-
Q10.A transformer works on the principle of:
Show answer & explanation
Answer: D — Mutual induction
A changing current in one coil induces a voltage in the other.
How to approach physics questions
Write the formula before substituting and keep SI units throughout. Most numerical questions use one of: v = u + at, s = ut + ½at², F = ma, KE = ½mv², V = IR, P = I²R.
