A water drop is divided into 8 equal droplets. The pressure difference between the inner and outer side of the big drop will be

Options

  1. Asame as the smaller droplet.
  2. Bhalf of that for smaller droplet
  3. C( 1 4 )^ th of that for smaller droplet.
  4. Dtwice that for smaller droplet

Correct answer

B. half of that for smaller droplet

Step-by-step solution

Volume of 8 smaller drops = Volume of the bigger drop array ll & 8 4 3 r^3= 4 3 R^3 & 2 r=R or r= R 2 array aligned & Excess pressure (P_i-P_o )= 2 T r & P_s= T 2 r , P_B= T 2 R & P_B P_S = r R = 1 2 & P_B= P_S 2 aligned
