Question

(1) : If a body moving in a circular path has a constant speed, then there is no force acting on it.
(2) : The direction of the velocity vector of a body moving in a circular path is changing.

• A. Both (1) and (2) are true and (2) is the correct explanation of (1)
• B. Both (1) and (2) are true but (2) is not the correct explanation of (1)
• C. (1) is true but (2) is false
• D. (1) is false but (2) is true

Answer 1

The correct option is D (1) is false but (2) is true

(A) For a body moving in a circular path at constant speed, the centeripetal force is always present on the body acting towards the center.
(B) Direction of the velocity vector of a body, moving in a circular path, always keeps on changing or the position vector of the particle keeps on changing.
