The length of mercury column in the barometer tube is 150 cm.
Explanation:
- We are not changing the atmospheric pressure.
- So height of Hg from the surface should not change.
75 / x = cos(60°) [ since cos(60°) = 1/2]
75/x = 1/2
75 x 2 = x
x = 150 cm
Hence the length of mercury column in the barometer tube is 150 cm.
