A body is revolving with a constant speed along a circle. If its direction of motion is reversed but the speed remains the same, then which of the following statement is true

AThe centripetal force will not suffer any change in magnitude

BThe centripetal force will have its direction reversed

CThe centripetal force will not suffer any change in direction

DBoth $(a)$ and $(c)$

Solution

(d) Centripetal force = $\frac{{m{v^2}}}{r}$ and is directed always towards the centre of circle. Sense of rotation does not affect magnitude and direction of this centripetal force.
