Because mercury is also a type of liquid, and the plane of all liquids segment (move downward) due to surface tension force in open tubes.

Ram Kumar said:   1 decade ago
It happens due to surface tension force, which works on liquid surface in open tubes.

No, the curve is upward because it is very dense and the cohesion is very high. So the answer is wrong.

I agree that the given option is Correct.

I think it is convex upward.

Pratik Deshmukh said:   9 years ago
I agree with the answer B.

Because cohesive force in mercury is more than adhesive.

It goes down that goes downward, but the shape of the curve is convex i. e upwards.

Anand rai said:   9 years ago
I think, Option B is correct.

Baloch said:   9 years ago
It should be curved upward.

Because lack of adhesive force.

The curve is downward in case of water where meniscus is formed.
