The three charges q 2 , q and q 2 are placed at the corners A , D and C of a square of side a as shown in figure. The magnitude of electric field E at the corner B of the square, is

Question

Aicharya · Accepted Answer

E A = k q 2 a 2 = k q 2 a 2 , E C = k q 2 a 2 = k q 2 a 2 and E D = k q 2 a 2 = k q 2 a 2 As we can see from diagram, E C &#160; &#38; &#160; E A are perpendicular. Therefore, net electric field will be, = k q 2 a 2 + k q 2 a 2 2 + k q 2 a 2 2 = k q 2 a 2 + k q 2 a 2 = q 4 &#960; &#1013; 0 a 2 1 2 + 1 2
