Q. In the above question, if the angular velocity is kept same but the radius of the path is halved, the new force will be
A) $2F$
B) $F^{2}$
C) $F/2$
D) $F/4$
Explanation
(c) $F = m\omega^{2}R\ \therefore F \propto R$ ( $m$ and $\omega$ are constant)
If radius of the path is halved, then force will also become half
