The excess of pressure, due to surface tension, on a spherical liquid drop of radius ‘R’ is proportional to

Options

  1. AR - 1
  2. BR
  3. CR - 2
  4. DR 2

Correct answer

A. R - 1

Step-by-step solution

The excess of pressure due to surface tension on a spherically liquid drop is given by p = 2 T R ….(i) where, T = surface tension and R = radius of liquid drop. So, from Eq. (i), we get p ∝ 1 R o r p ∝ R - 1
