Question

When a body P moves on a circular path, the centripetal acceleration is

(a) directed inwards from P, to the centre of the circle

(b) directed tangential to the circumference of the circle, at P

(c) directed perpendicular to the planc of the circle, at P

(d) directed outward, perpendicular to the circumference of the circle​

Answer 1

Answer:

An object moving in a circle is experiencing an acceleration. This acceleration is directed towards the centre of the circle an object which experiences an acceleration must also be experiencing a net force. The direction of the net force is in the same direction as the acceleration. So for an object moving in a circle, there must be an inward force acting upon it in order to cause its inward acceleration. This is sometimes called as centripetal force.

so,The direction of acceleration of an object moving in a circular path is directed towards the centre of the circle. 

Hence,option B IS CORRECT
