SUMMARY
The discussion centers on calculating the magnitude of the electric field at point P due to a charge of Q=80nC, located 3.0m and 4.0m away from point P. The correct formula for electric field (E) is E=k*Q/R^2, where k is Coulomb's constant. To find the total electric field at point P, one must calculate the electric field contributions from each charge separately and then vectorially add these fields, as they will point in different directions.
