A cylinder of radius 4cm and height 10cm is immersed in two liquids as shown. Specific gravity of oil is 0.5. 2cm of cylinder is in the air. Select the incorrect statement. Neglect atmospheric pressure.

Options:

Answer:

Solution:

Force exerted by oil on the cylinder is zero. Force by water $= (4 σ g + 4 ρ g) \times A$

$= [4 \times \frac{1}{2} \times \frac{1 0 ^{4}}{100} + \frac{4 \times 1 0 ^{3} \times 10}{100}] \times \frac{16 π}{1 0 ^{4}} = 0.96 π N$
