Solution

The correct options are
B
P $_{2}$ >P $_{1}$

C
P $_{2}$ = hρg + P $_{1}$

Since point A is at the surface and point B is inside the water at a depth of h.

P $_{2}$ will be greater than P $_{1}$

P $_{2}$ = hρg + P $_{1}$

Note : since point A is on the surface, so P $_{1}$ = Atmospheric pressure at A

And since point B is at a certain depth, P $_{2}$ =Atmospheric pressure at A + Pressure exerted by the liquid on point B.
