A force F is applied on the plank such that the hollow hemispherical shell is in equilibrium as shown in the figure. The coefficient of friction μ is the same between the hemispherical shell and the plank as it is between the plank and the ground. Friction is just sufficient to prevent the slipping (Take g=10 m s-2 and m=5 kg). Then
