Body 1 has a mass m, and its moving in a circle with a radius r at a speed v. It has a centripetal force. F acting on it. If body 2 has a mass 2m and its moving in a circle of radius 4r at a speed 4v, what is the centripetal force acting on it

The centripetal force on body 2 is 8 times of the centripetal force in body 1.

Explanation:

Body 1 has a mass m, and its moving in a circle with a radius r at a speed v. The centripetal force acting on it is given by :

Body 2 has a mass 2m and its moving in a circle of radius 4r at a speed 4v. The centripetal force on body 2 is :

So, the centripetal force on body 2 is 8 times of the centripetal force in body 1.
