please give explanation

Answer 1

Answer:

Given,

Weight of body in water is

3

1

of total weight in air,

Mean, buoyancy force in water is

3

2

of total weight in air

Volume of body, V

Density of water & body, ρ

w

& ρ

b

Apply Archimedes principle

Buoyancy force = weight of water displaces =
