Answer:
Option (a) is the correct answer
Explanation:
Option (a) smaller than P is the correct answer for the given question. This is because the pressure (P) at any depth 'd' from the top surface of the water with density (ρ) is given as:
P = ρ × g × d
where,
g is the acceleration due to the gravity
thus from the above equation it can be concluded that the pressure at any depth 'd' is directly proportional to the density of the water.
thus,
in the given case the density of the water is lower than that in the first case.
Hence, the option (a) is the correct answer
