Question

A body is fully immersed in the water. Which of the following will result in the increase of pressure exerted on the bottom surface of the body?

• A. Increasing the density of water
• B. Increasing the height of water
• C. Increasing the density of the body
• D. Increasing the air pressure above water

Answer 1

Answer: (A), (B), (D)

The correct options are
A Increasing the density of water
B Increasing the height of water
D Increasing the air pressure above water

Pressure on a body at a depth $h$ is:
$P=P_{atm}+\rho gh$

$P_{atm}:$ atmospheric pressure,
$g:$ acceleration due to gravity
$\rho$: density of water

We can conclude from the above equation that increasing atmospheric pressure, height and density of water will increase the pressure on the surface of the body. Changing the density of body itself will not affect the pressure.
