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
- 2
- 3
- 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 
so net electric field at M, 
in the direction of vector 2.
