Question

body weighs 250 gf in air and 210 gf when completely immersed in water , Calculate : i. the upthrust on the body. the volume of the solid.​

Answer 1

in this answer the value is not same

Explanation:

Weight of the body in air =500gf

Weight of the body in water =450gf

∴ (i) loss of weight of the body when immersed in water =500gf−450gf=50gf.

(ii) upthrust of the body=loss in weight of the body =50gf.

(iii) upthrust =Vdg

⇒50gf×g=V×1gcm
