Problem

A 4 kg4\,\text{kg} block rests on a rough horizontal table. A horizontal force of 10 N10\,\text{N} is applied to the right, yet the block does not move. Which statement about the frictional force acting on the block is correct? (a) It acts to the left with magnitude μsR\mu_s R. (b) It acts to the right with magnitude 10 N10\,\text{N}. (c) It acts to the left with magnitude 10 N10\,\text{N}. (d) It acts to the right and equals μsR\mu_s R.
