Mercury does not wet glass - the cohesive forces within the drops are stronger than the adhesive forces between the drops and glass.

@Meet.

Cohesion, adhesion, and surface tension are properties of capillarity. But the answer should be Cohesion.

Mohit said:   7 years ago
It should be A.

Meet said:   7 years ago
The surface tension is due to cohesion only and in question 'PROPERTY OF FLUID' (cohesion is FORCE)is asked. So the answer is surface tension.

As the cohesion is more than the adhesion so it doesn't wet the glass.

Angle of contact is obtuse.

Karan sharma said:   8 years ago
Surface tension is binary property Adhesion and cohesion. But main reason is cohesion behind it.

As per my opinion, the correct answer, Cohesion and Surface Tension: Both Option are correct.

Waseem said:   8 years ago
You are right @Sharad.

Surface tension is only due to cohesive property of fluid.

Sharad said:   9 years ago
Surface tension is due cohesion only. So it is same.

Ram said:   9 years ago
Yes, option A is right.
