A skier of mass \( M \) slides down a ramp shaped as a circle of radius \( R \). At the end point of the ramp just before the skier is in the air, the magnitude of the normal force exerted by the ramp on the skier is \( \mathrm{N} \). The acceleration due to gravity is g. Then :-
(1) The magnitude of the normal force \( \mathrm{N} \) is greater than \( \mathrm{Mg} \)
(2) The magnitude of the normal force \( \mathrm{N} \) is equal to \( \mathrm{Mg} \)
(3) The magnitude of the normal force \( \mathrm{N} \) is less than \( \mathrm{Mg} \)
(4) The magnitude of the normal force \( \mathrm{N} \) can be greater than, equal to, or less than \( \mathrm{Mg} \) depending on the speed of the skier.
