Four identical charged particles (g = +20.0 μC) are located on the corners of a rectangle as shown in the figure below. The dimensions of the rectangle are L = 57.0 cm and W = 14.0 cm. Calculate the change in electric potential energy of the system as the particle at the lower left corner in the figure is brought to this position from infinitely far away. Assume the other three particles in the figure below remain fixed in position. J W

Expert Solution
Introduction:
We are given 4 charges which are identical. We are also given value of this charge. We have to find the change in potential energy when left bottom corner charge is brought with the other 3 charges at corners. This change is equal to work done in bringing this charge from infinity to this point against field of each charge.
