If the shape of the liquid surface is curved, then

Options

  1. Athe pressure on convex side is equal to atmosphereic pressure.
  2. Bthe pressure on the convex side is equal to pressure on concave side.
  3. Cthe pressure on the concave side is greater than that on the convex side.
  4. Dthe pressure on the concave side is lesser than that on the convex side.

Correct answer

C. the pressure on the concave side is greater than that on the convex side.

Step-by-step solution

When a liquid surface is curved, there is a pressure difference across the surface due to surface tension. The pressure on the concave side of the curved surface is always greater than the pressure on the convex side. The excess pressure is given by P = 2T R , where T is the surface tension and R is the radius of curvature. Therefore, the pressure on the concave side is greater than that on the convex side. Answer: the pressure on the concave side is greater than that on the convex side.
