Four point charges have the same magnitude of 2.47 10-12 C and are fixed to the corners of a square that is 3.65 cm on a side. Three of the charges are positive and one is negative. Determine the magnitude of the net electric field that exists at the center of the square.

The electric field of the two positive charges opposite to each other would cancel each other out.

The electric field of -ve charge and its opposite positive charge will add up in the direction towards the negative charge.

distance from corner to center = r = 3.65/sqrt(2) = 2.58 cm

E by a charge q at a distance r is Kq/r2

Enet = 2Kq/r2

= (2*9*109*2.47*10-12)/(2.58*10-2)2

= 66.792 N/C
