Question

A body weighs 67 g-wt in air. It displaces 11 g-wt water when completely immersed in it. What is the buoyancy on the body? a) 11 g-wt b) 12 g-wt c) 56 g-wt d) 67 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
