A cubical block of steel of each side equal to

l

is floating on mercury in a vessel. The densities of steel and mercury are

\rho_s

and

\rho_m

. The height of the block above the mercury level is given by

View answer and explanation

Correct option: B

l\left(1-\frac{\rho_s}{\rho_m}\right)

Option B (

l\left(1-\frac{\rho_s}{\rho_m}\right)

) is correct because it represents the height of the block above the mercury level, calculated using the principle of floatation.
