A. Positive point-charges of +36.0 mC (Micro C) are fixed at two of the vertices of an equilateral triangle with sides of 3.30 m, located in vacuum. Determine the magnitude of the E-field at the third vertex.
B. Redo the last problem, this time with charges of +36.0 mC (Micro C) and -36.0 mC (Micro C) at either end of the baseline (creating the field at the remaining vertex).
