In a U-tube experiment, a column AB of water is balanced by a column CD of paraffin. The relative density of paraffin is

A

`(h_(2))/(h_(1))`

B

`(h_(1))/(h_(2))`

C

`(h_(2)-h_(1))/(h_(1))`

D

`(h_(2))/(h_(1)+h_(2))`

Text Solution

Verified by Experts

The correct Answer is:
A
Pressure is same in a horizontal level, `p_(D)=p_(B)`
`therefore p_(0)+rho_(1)gh_(1)=p_(0)+rho_(w)gh_(2)`
or `(rho_(1))/(rho_(w))`=relative density of paraffin`=(h_(2))/(h_(1))`
