A body weighs 450 gf in air and 310 gf when completely immersed in water. Find:
(i) the volume of the body
(ii) the loss in weight of the body, and
(iii) the upthrust on the body. State the assumption made in part (i)

Text Solution

Verified by Experts

Up thrust = difference in weight =450-310
=140 gf
