If the shape of the liquid surface is curved, then (a) the pressure on convex side is equal to atmosphereic pressure. (b) the pressure on the convex side is equal to pressure on concave side. (c) the pressure on the concave side is greater than that on the convex side. (d) the pressure on the concave side is lesser than that on the convex side.

Answer: (c). Surface tension pulls a curved surface towards its centre of curvature, i.e. towards the concave side. For equilibrium the pressure on the concave side must exceed that on the convex side by 2T/R. So the answer is (c) the pressure on the concave side is greater.

If the shape of the liquid surface is curved, then

Show answer and solution

Answer: (c)

Surface tension pulls a curved surface towards its centre of curvature, i.e. towards the concave side.
For equilibrium the pressure on the concave side must exceed that on the convex side by $\frac{2T}{R}$ .
So the answer is (c) the pressure on the concave side is greater.
