In a given U-tube (open at one-end) find out relation between p and `p_(a)`
Given `d_(2)=2xx13.6gm//cm^(3),d_(1)=13.6gm//cm^(3)`

Text Solution

Verified by Experts

Pressure in a liquid at same level is same i.e., at `A - A-`,
`P_(a) + d_(2)yg + xd_(1)g = P`

In C.G.S.
`P_(a) + 13.6 xx 2 xx 25 xx g + 13.6 xx 26 xx g = P`
`P_(a) + 13.6 xx g [50 + 26] = P`
`2P_(a) = P [P_(a) = 13.6 xx g xx 76]`
