Q. 20

The direction of acceleration of an object moving in a circular path is:
A. directed away from the centre of the circle

B. directed towards the centre of the circle

C. directed upward in the plane of the circle

D. none of these

Answer :

The direction of acceleration of an object having a circular path is directed towards the center of circle.

This acceleration is called the centripetal acceleration. This centripetal acceleration produces centripetal force to change the direction of the object, so that it moves on a circular path.

In the above figure: ac = Centripetal Acceleration and v = Speed of Object.

Hence option B is correct.
