A body weighs 200 gf in air and 175 gf when it is completely immersed in water. The buoyancy force acting on it is
2.5 kg
25 g
2.5 g
25 kg
Buoyancy force = True Weight - Apparent weight
FB = W - W'
= (200 - 175) gf = 25 g
A solid weighs 100 gf (gram force) in air and 90 gf (gram force) when completely immersed in water. Calculate the volume of the solid.
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).
