Answer #1

(1) In hydraulic lifting work done is same for both the pistons. Thus, given statement is false.

Reason:

since pressure is same for both the pistion;

where A1 and A2 are the area of cross section of piston;

these areas are inversely proportional to the displacement of piston as;

compare equation (1) and (2)
