A block of mass 2 kg is pushed against a rough vertical wall with a force of 40 N, coefficient of static friction being 0.5. Another horizontal force of 15 N, is applied on the block in a direction parallel 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.

Hi H V,

if the image is downloaded then follow this link for image file.:

the block will move because the net force due to weight and horizontal force is 25N which is more than the friction force 20 N....... the block will move downward at an angle of tan-1(15/20)
