Question

. A body weighs 82 g-wt in air. It displaces 14 g-wt when completely immersed in it. What is the apparent weight

of the body?

a) 65 g-wt

b) 68 g-wt

c) 86 g-wt

d) 90 g-wt​

Answer 1

Apparent weight,

W′ =W−F

(Where 'F' is buoyancy force which is equal to weight of displaced liquid.)

Apparent weight,

14g = 82g−F

F = 82 - 14

F = 68 g-wt
