If you know the centripetal force acting on an object moving in a circle, which equation will allow you to calculate the velocity of the object

The velocity of the object in circular motion,

Explanation:

The second law of motion given the magnitude of force acting on an object. It is equal to the product of its mass and acceleration i.e.

..........(1)

In a circular path the acceleration of the object is called centripetal acceleration,

Equation (1) becomes,

We know that, in circular motion the force acting on the object is centripetal force. The formula for centripetal force is given by :

So, the correct option is (a). Hence, this is the required solution.
