Question

Match column I with column II and select the correct answer using the codes given below:
Column I Column II
(A) F = constant$\ne$0 (p) Directional change
(B) F = 0 (q) Variable acceleration
(C) F$\ne$ constant (r) No change in momentum
(D) F$\ne$ 0 (s) If a body moves uniformly along a circle

• A. A - (p); B - (s); C - (q); D - (r)
• B. A - (q); B - (p); C - (r); D - (s)
• C. A - (p); B - (r); C - (q); D - (s)
• D. A - (s); B - (q); C - (p); D - (r)

Answer 1

The correct option is C A - (p); B - (r); C - (q); D - (s)

Answer is C.
A moving object with a constant force keeps moving at the same speed and in the same direction.
An object with zero force, there will be no change in the momentum.
If the resultant force acting on an object is not zero or constant, a stationary object begins to accelerate in the same direction as the force. A moving object speeds up, slows down or changes direction.
A moving object with force not equal to zero, the object moves uniformly in a circular motion.
