A lift is moving downward with an acceleration equal to 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 μ, then the frictional resistance offered by the body is

Hi...
(N = normal, m = mass of object, a = acceleration of lift)
mg - N = ma
N = ma - mg
(given a = g)
therefore
N= 0
friction = u.N (N = 0)
hence friction = u.0
= 0
Hope this helps u!!
