Four point charges, each of magnitude q,are located at the corners of a square with sides of length a. Twoof the charges are +q, and two are -q. The charges are arrangedin one of the following two ways: (1) The charges alternate in sign1+q, -q, +q, -q2 as you go around the square; (2) the top two corners of the square have positive charges 1+q, +q2, and the bottomtwo corners have negative charges 1-q, -q2. (a) In which case willthe electric field at the center of the square have the greatest magnitude? Explain. (b) Calculate the electric field at the center of thesquare for each of these two cases.

Electric Charges and Fields

One of the fundamental properties is the electromagnetic property. Charge cannot be destroyed by any process and this contributes formally to the law of charge conservation.
