In the above question, if the lift is moving upwards with a uniform velocity, then the frictional resistance offered by the body is

A body is moving with uniform velocity —

When a body moves with uniform velocity then

A body moving with uniform velocity

A lift is moving upwards with a uniform velocity v in which a block of mass m is lying: The frictional force offered by the block when the coefficient of friction is mu will be

A lift is moving down with an acceleration equal to the acceleration due to gravity. A body of mass M kept on the floor of the lift is pulled horizontally. If the coefficient of friction is mu then the frictional resistance offered by the body is:
