Question

If the system is not in free fall, which of the following statements is true about hydrostatic pressure?

• A. In a liquid, point at different depth can never be at the same pressure.
• B. In a liquid, point at different depth may be at the same pressure.
• C. In different liquids, points at different depths can be at the same pressure.
• D. In different liquids, points at the same depths can never be at the same pressure.

Answer 1

Answer: (A), (C), (D)

The correct options are
A In a liquid, point at different depth can never be at the same pressure.
C In different liquids, points at different depths can be at the same pressure.
D In different liquids, points at the same depths can never be at the same pressure.

pressure for same liquid is $\rho gh$

at same depth pressure is same as for specific liquid density is constant and depth is same

for different liquid

pressure at different depth can be same as $\rho h$ can be constant for different liquid

but for different liquid pressure at same depth cannot be same as density is different and depth is same so pressure cannot be same
