A wedge is placed on a smooth horizontal surface. Wedge contains a circular quadrant of radius 25 cm as shown. An insect crawls on the circular part with a constant speed 0.5 m/s. A force F is applied on the wedge, so that it does not move. Find the value of F in newton when radial line of position of insect makes an angle 60o with horizontal.
