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

The convexity upward.

The bent portion will be an upside.

So, the curve upward is the right option.

The fluid falls down due to strong cohesion but its shape is curved downwards. So the answer is B.

Muhammad Saqib said:   6 years ago
I think it should be option B, because cohesion is more than adhesion, same as a case in water.

B GURUNATH said:   8 years ago
I think answer B is correct.

Because cohesion property is more than the adhesive property.

Tanmoy Karmakar said:   6 years ago
B is the correct.

Curved Upward because mercury has a high cohesive value than adhesion.

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

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.

Suri said:   7 years ago
Mercury in free surface means it takes convex shape. So, B is the right answer.
