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

Options

A. In a liquid, points at different depths can never be at the same pressure.
B. In a liquid, points at different depths 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 depth can never be at same pressure.

Answer

A, C, D

Explanation

If the system is not in the state of free fall, pressure at any point in a liquid depends on its depth `h` w.r.t its ree surface.
`P=P_(0)+hdg`
i.e, pressure is difference at points lying in different depths in the liquid. In different liquids (i.e., density `d` is different ) points at the same dept `h` will be at different pressues. but points lying at differentt depths in different liqids can be at the same pressure if
`h_(1)d_(1)=h_(2)d_(2)`.............
