A block A of mass M is placed on horizontal table. Another block B of mass m is places on block A as shown in figure. Now F force is applied on B. The conditions are explained below. 1. If there is no friction between A and B and between A and table, then B […]

Explore MoreFriction: Friction is the retarding force which acts tangentially to the contact surface when a body actually moves or tends to move over the surface of another body. Static friction: The force of friction which exactly counter-balance the applied force during the stationary state of a body is called static friction. So static friction is […]
