A block of mass 2 kg is pushed against a rough vertical wall with a force os 40 N. Coefficient of static friction being 05. Another horizontal force is 15 N, is applied on the block in a direction paralle to the wall. Will the block move? If yes in which direction? If no, find the frictional force exerted by the wall on the block.
