Question

a block of mass M is kept on the floor of a free falling lift during free fall of the left the block is pulled horizontally with a force of 2 coefficient is equal to 0.1 the frictional force on the block is​

Answer 1

Answer:

zero

Explanation:

normal force on the block will be zero.

so friction force = 0

Answer 2

Answer:0

Explanation:

Given

A block of mass M is kept on the floor of a free falling lift i.e. there is no normal reaction between block and lift

i.e. N=0

and friction force  is given by

$f_r=\mu N=0.1 \times 0=0$
