In Fig. 7.149 , coefficient of friction between the block and the floor is `mu` . Force F that will move the block on the floor with a uniform speed is :

A block of mass'm' is placed on floor of a lift which is rough. The coefficient of friction between the block and the floor is mu . When the lift falls freely, the block is pulled horizontally on the lift floor. The force of friction is

A block of mass m is placed on a rough floor of a lift . The coefficient of friction between the block and the floor is mu . When the lift falls freely, the block is pulled horizontally on the floor. What is the force of friction -

A block of mass m slips on a rough horizontal table under the action of horiozontal force applied to it. The coefficient of friction between the block and the table is mu . The table does not move on the floor. Find the total frictional force aplied by the floor on the legs of the table. Do you need the friction coefficient between the table and the floor or the mass of the table ?
