Question

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 1

The correct option is B directed towards the centre of the circle

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.
