Question

Which statement is true about an object that is moving in a circular motion due to centripetal force, F, when the radius of its circular motion is doubled?
The new force then becomes equal to 2F
The new force then becomes equal to F
The new force then becomes equal to F/2
The new force then becomes equal to F2
The new force then becomes equal to 1/F

Answer 1

The force becomes 1/2 F which is the third choice

F=mv^2/r
