Force responsible for the circular Morton of the body is:

A) centripetal force             

B) centrifugal force

C) gravitational force          

D) none of these

Correct Answer: A

Solution :

A body performing circular motion is acted upon by a force which is always directed towards the centre of the circle. The force is called centripetal force. In the absence of this force the circular motion is not possible. If m is the mass of the body and v is velocity and r is radius then magnitude of centripetal force is \[F=\frac{m{{v}^{2}}}{r}\]
