Two electric dipoles, each of dipole moment ' P ' are placed at points A(a, 0) and B(-a, 0) as shown in the figure. The work done in rotating both the dipoles through 90^ in clockwise direction is (E= Electric field )

Options

  1. APE
  2. BZero
  3. C2 PE
  4. DP E 2

Correct answer

A. PE

Step-by-step solution

Work done due to dipole, W =- p E Here W = W ₉₀- W ₀=(- PE 90)-(- pE 0)= PE
