Two points A and B are at distances of ' a ' and ' b ' respectively from an infinite conducting plate having charge density . The work done in moving charge Q from A to B is

Options

  1. AQ ₀ (b-a)
  2. B(b-a) Q
  3. CQ (b-a) ₀
  4. Dnone of these

Correct answer

A. Q ₀ (b-a)

Step-by-step solution

aligned & = ₀ & ~V _ A - V _ B = ₀ ( ~b )- ₀ ( a ) & W = Q ( V _ A - V _ B )= Q ₀ ( ~b - a ) aligned
