A block of mass m is kept on the floor of a freely falling lift. During the free fall of the lift, the block is pulled horizontallywith a force of 2 N, mew s=0.1. The frictional force on the block will be

Dear Student

As we know for a free falling lift g' =geff = g-g = 0Hence Asg' =0Normal = 0Andf = μN = 0Therefore zero friction would be applicable
