Barometer is constructed using liquid . What would be height of liquid column when mercury barometer reads 76cm

A

13.6m

B

136m

C

0.76m

D

1.36m

Text Solution

Verified by Experts

The correct Answer is:
A
According to the question
`76cm xx rho_(Hg)xx g= h xx rho_(L) xx g`
`h= 76cm xx (rho_(Hg))/(rho_(L)) = 76cm xx (13600)/(760)= 13.6cm`
