Question

Find the electric field at the center of an equilateral triangle

Answer 1

Answer:

The ‘electric field’ intensity at the ‘centroid of the triangle’ will be 0.

Explanation:

Electric field due to +Q charges of edge A, B and C at center is,

As shown in figure,  

Resultant of ,  

But as

Here as are equal in magnitude and in opposite direction, so electric field at o is zero.
