Question

Three identical point charges, as shown are placed at the vertices of an isosceles right angled triangle. Which of the numbered vectors coincides in direction with the electric field at the mid-point M of the hypotenuse

  1. 1    
  2. 2    
  3. 3    
  4. 4    

The correct answer is: 2


    EA = Electric field at M due to charge placed at A
    EB = Electric field at M due to charge placed at B
    EC = Electric field at M due to charge placed at C

    As seen from figure Error converting from MathML to accessible text. so net electric field at M, Error converting from MathML to accessible text. in the direction of vector 2.
