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?

(A) The new force then becomes equal to 2F
(B) The new force then becomes equal to F
(C) The new force then becomes equal to F/2
(D) The new force then becomes equal to F^2
(E) The new force then becomes equal to 1/f

Answer 1

Answer is if you double the radius you will halve the force or (C) The new force then becomes equal to \[ \frac{ F }{ 2 }\]
