' n ' small drops of same size are charged to 'V' volt each. If they coalesce to form a single large drop, then its potential will be

Options

  1. AVn ^ 1 3
  2. BVn ^ 2 3
  3. CV n
  4. DVn ⁻¹

Correct answer

B. Vn ^ 2 3

Step-by-step solution

V = 1 4 ₀ q r aligned V ^ & = 1 4 ₀ q ^ r ^ & = 1 4 ₀ nq n ^ 1 / 3 r ( q ^ = nq , r ^ = n ^ 1 / 3 r ) V ^ & = Vn ^ 2 / 3 aligned
