Q: Which of the following is a scalar quantity?
A) Force
B) Acceleration
C) Velocity
D) Speed
✅ Correct Answer: D
Explanation: Speed has only magnitude, not direction, making it a scalar.
Q: Which has more inertia?
A) A feather
B) A pen
C) A truck
D) A book
✅ Correct Answer: C
Explanation: Greater mass implies greater inertia, so a truck has the most.
Q: Work is zero when angle between force and displacement is?
A) 90°
B) 180°
C) 45°
D) 0°
✅ Correct Answer: A
Explanation: Cosine of 90° is zero, hence no work is done.
Q: Which law gives relationship between voltage, current and resistance?
A) Hooke's Law
B) Boyle's Law
C) Newton's Law
D) Ohm's Law
✅ Correct Answer: D
Explanation: Ohm’s Law: V = IR.
Q: A body moving in circle with constant speed has?
A) Increasing velocity
B) Centripetal acceleration
C) Constant acceleration
D) No acceleration
✅ Correct Answer: B
Explanation: Velocity changes direction, causing centripetal acceleration.
