frictional force?
OA 20 newtons in the direction of the applied force
20 newtons opposite to the direction of the applied force
Oc. 20 newtons perpendicular to the direction of the applied force
OD. 20 newtons in two directions, perpendicular and in the direction of the applied force
OE. No friction is acting on the block.
