This document compares two situations involving charges placed at opposite corners of a square. In Situation 1, a -q charge is at one corner and a +q charge is at the other corner. In Situation 2, charges are placed at the empty corners instead of the center. The electric force, field, and potential are equal or greater at the corners compared to the center in both situations.

1. 8. Use , to compare these situations. A charge of -q and a charge of +q are placed at opposite
cormers of a uare Situation 1 Situation 2 The magnitude of the electric force on a proton placed
at one of the empty cormers The magnitude of the electric field at one of the empty corners The
electric potential at one of the empty The magnitude of the electric force on a proton placed in
the center of the square The magnitude of the electric field at the center of the square The electric
potential at the center of the square cornerS +4
Solution
Situation 1 Situation 2
electric force = electric force
electric field < electric field
electric potential < electric potential
