A body of mass 2 kg is kept by pressing to a vertical wall by a force of 100 N . The coefficient of friction between wall and body is 0.3. Then the frictional force is equal to

Frictional force between two bodies

Frictional force between two bodies

Frictional force between two bodies

A block of mass 2kg is held at rest against a rough vertical wall by passing a horizontal (normal) force of 45 N . Coefficient of friction between wall and the block is equal to 0.5. Now a horizontal force of 15 N (tangential to wall) is also applied on the block. Then the block will :
