Question

Two particle of charge q1 and q2 are separated by distance d as shown in figure. Charge q1 is situated at the origin. The net electric field due to the particle is zero at x = d/4. With V = 0 at infinity, the location of a point in terms of d on the x axis (other than at infinity) at which the electrical potential due to the two particle is zero, is given by:

  1. d/4    
  2. 16 d    
  3. – 16 d    
  4. no point on the axis    

The correct answer is: no point on the axis



    both positive so no point except ¥
