A block of mass \( m \) is revolving in a smooth horizontal plane with a constant speed \( \nu \). If the radius of the circular
P path is \( R \), find the total contact force received by the block.

W
(1) \( \frac{m v^{2}}{R} \)
(2) \( m g \)
(3) \( m \sqrt{\frac{v^{4}}{R^{2}}+4 g^{2}} \)
(4) \( m \sqrt{\frac{v^{4}}{R^{2}}+g^{2}} \)
