Question

prove:
1) p=dhg
.........
​

Answer 1

Explanation:

P = F/A

P = mg/A [ since F = mg ]

P = Vdg/A [ since m = Vd ]

P = Ahdg/A [ since V = Ah ]

P = hdg

Answer 2

Explanation:

Let us assume

P= pressure

d= density

H= height

g= acceleration due to gravity

by the formula of Pressure

p=f/a = mg/a

p=d×v×g/a

p=d×a×h×g/a

p=dhg proved.
