Question

A man standing in an elevator that is moving downward with a constant acceleration and holding (in air) a 3kg3kg block 'B' between two other blocks (A and CC) by pushing horizontally from both sides in such a way that the motion of B relative to A and CC is impending. Knowing that the coefficient of friction between all surfaces are μs=0.3μs=0.3 and μk=0.25μk=0.25 Max. Horizontal forces exerted by man on each blocks AA and CC are 30 Newton. The acceleration of elevator cannot be
