Question

A block of mass 1 kg is placed on the rough floor of a lift. The coefficient of friction between the
block and the floor is 0.3. When the lift falls freely, the block is pulled horizontally on the floor.
What will be the force of friction (in N)?

Answer 1

Answer:

zero

Step-by-step explanation:

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 μ . When the lift falls freely , the block is pulled horizontally on the lift floor. The force of friction is
