in previous question, if 15 cm of water and spirit each are further poured into the respective arms of the tube. Difference in the level of mercury in the two arms is (Take, relvative density of mercury = 13.6)

Text Solution

Verified by Experts

The correct Answer is:
A, B, C, D
`(p_(0)+rho_(w)h_(w)g)-(p_(0)+rho_(s)h_(s)g)=rho_(Hg)h_(Hg)g`
`:. h_(Hg)=(rho_(w)rho_(w)-rho_(s)h_(s))/(rho_(Hg))`
`=((1)(25)-(0.8)(27.5))/(13.6)`
`=0.221 cm`.
