When a mercury drop of radius 'R', breaks into 'n' droplets of equal size, the radius 'r' of each droplet is

Options

  1. Ar = R n
  2. Br = R n
  3. Cr = R n ^ 1 3
  4. Dr = R n ^ 1 3

Correct answer

C. r = R n ^ 1 3

Step-by-step solution

Volume remains constant n 4 3 r ³= 4 3 R ³ nr ³= R ³ n^ 1 3 r=R r= R n^ 1 3
