प्रश्न
A block of mass m is kept on a horizontal table. If the static friction coefficient is μ, find the frictional force acting on the block.
उत्तर
A block of mass m is kept on a horizontal table. If force is applied on the block, a friction force will be there: p → frictional force and F → applied force
So, friction force is equal to the applied force. One of the case is that the friction force is equals to zero when the applied force is equal to zero.
