A force which acts on an object moving in a circle and is directed towards the center of the circle is called:
Correct answer: B. Centripetal Force
- A. Bending Force
- B. Centripetal Force
- C. Centrifugal force
- D. None of these
Explanation
A 'centripetal force' is a force that makes a body follow a curved path. Its direction is always orthogonal to the motion of the body and towards the fixed point of the instantaneous center of curvature of the path.

About Angular and Linear Quantities
Rotational motion relates angular displacement, angular velocity and angular acceleration to linear displacement, tangential velocity and tangential acceleration through the radius. Questions use radians, v equals r omega and tangential acceleration, while distinguishing tangential velocity from centripetal acceleration and angular quantities from their linear counterparts.
