A block of mass 0.1 kg is held against a wall by applying a horizontal force of 5 N on the block. If the coefficient of friction between the block and the wall is 0.5, the magnitude of the frictional force acting on the block is

Answer: (B)

Solution

Normal force N = applied force = 5 N; maximum friction = μN = 0.5×5 = 2.5 N. Since the block's weight
