A body of weight 50 N is placed on a smooth surface. If the force required to move the body on the rough surface is 30 N the coefficient of friction is

A body of weight 50 N is placed on a smooth surface. If the force required to move the body on the surface is 30 N the coefficient of friction

In the figure, a block of weight 60 N is placed on a rough surface. The coefficient of friction between the block and the surface is 0.5. The minimum weight of the block does not slip on the surface is (x xx 10) N. The value of x is
