MHT CET 2026 Physics question

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.Correct
(D)the pressure on the concave side is lesser than that on the convex side.

Answer: (C)

Solution

Surface tension makes a curved liquid surface behave like a stretched membrane, and the surface-tension force has a resultant directed towards the centre of curvature. For equilibrium, the pressure must be larger on the concave side (the side containing the centre of curvature) than on the convex side; the excess
