When mass and speed of a body is doubled the kinetic energy increases

If the mass of moving body is doubled, how many times will the kinetic energy increases ?

The centrpetal force acting on a body moving with uniform speed in circular path is 10 N. Without changing the path if the speed of the body is doubled, what will be the centripetal force ?
