(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

(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

anonymous · Answer

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