In the diagram, a force of 20 newtons is applied to a block. The block is in dynamic equilibrium. What is the magnitude and direction of the frictional force

A20 newtons in the direction of the applied force

B .20 newtons opposite to the direction of the applied force

C20 newtons perpendicular to the direction of the applied force
D20 newtons in two directions, perpendicular and in the direction of the applied force
ENo friction is acting on the block.
