Q: A small ball of density ρ is immersed in a liquid of density σ (σ > ρ ) to a depth h and released. The height above the surface of water upto which the ball will jump is

(a) $ \displaystyle (\frac{\rho}{\sigma}-1)h $

(b) $ \displaystyle (\frac{\rho}{\sigma}+1)h $

(c) $ \displaystyle (\frac{\sigma}{\rho}-1)h $

(d) $ \displaystyle (\frac{\sigma}{\rho}-1)h $

Ans: (c)
