A cube of side 5 cm is immersed in water and then in saturated salt solution. In which case will it experience a greater buoyant force? If each side of the cube is reduced to 4 cm and then immersed in water, what will be the effect on the buoyant force experienced by the cube as compared to the first case for water. Give reason for each case.
A ball weighing 4 kg of density 4000 kg m-3 is completely immersed in water of density 10^3 kg m-3. Find the force of buoyancy on it.
(Given g = 10 ms-2.)

Explanation:
cube of side 5 cm is immersed in water and then in saturated salt solution. In which
case will it experience a greater buoyant force. If each side of the cube is reduced to 4 cm
and then immersed in water, what will be the effect on the buoyant force experienced by
the cube as compared to the first case for water. Give reason for each case. (b) A ball
weighing 4 kg of density 4000 kg m–3
is completely immersed in water of density 103 kg m–3
Find the force of buoyancy on it. (Given g = 10 m s–2
.)
