Eight drops of mercury of equal radii and possessing equal charge combine to form a big drop. If the capacity of each drop is ' C '. then capacity of the big drop is

Options

  1. A4 C
  2. B2 C
  3. C8 C
  4. D16 C

Correct answer

B. 2 C

Step-by-step solution

Volume of big drop =8 volume of small drop 4 3 R^3=8 4 3 r^2 R=2 r Capacity of big drop, C ^ =4 ₀ R =4 ₀(2 r )=2 (4 ₀ r )=2 C
