Drops of liquid of density d are floating half immersed in a liquid of density . If the surface tension of the liquid is T , then the radius of the drop is

Options

  1. A3 T g(3 d- )
  2. B6 T g(2 d- )
  3. C3 T g(2 d-p)
  4. D3 T g(4 d-3 p)

Correct answer

C. 3 T g(2 d-p)

Step-by-step solution

According to the question, 4 3 r^3 d g= 2 3 r^3 g+T 2 r or r= 3 T g(2 d- )
