The electrical field as a result of a suggest charge at a distance is, Here is the Coulomb’s continuous, is the charge of the allude charge, and is the distance from the allude charge to the area point.

The arrangement of charges is presented in the listed below figure. The electrical area at allude as a result of the charge along the horizontal axis is, Here, is the distance of allude from the charge .

The electric field at point as a result of charge alengthy the horizontal direction is, Here, is equal to the size of the diagonal of the square. That is, is the distance of the point from the charge .

The electric area at suggest due to charge alengthy the vertical direction is, Because of this, the complete electric area at due to the charge is, Here, and are the unit vectors alengthy the horizontal and also vertical axes respectively.

The electrical area at because of the charge alengthy the vertical direction is, Here, is the distance of the point from the charge .

The net electric field at allude is the amount of the electrical fields because of the charges 3 charges in the corners of the square. Hence, the magnitude of the net field at allude is, The direction of the net electric area is The direction is counter-clockwise with the positive x axis.

The magnitude of the net electrostatic force is, Substitute for .
