Two point charges are separated by 25.0 cm (see (Figure 1)). Assume that q1 = -7.50 nC and q2 = -10.5 nC. Figure1 of 1Two negative point charges are placed on a dashed horizontal line. The charge on the left is q subscript 1, and the charge on the right is q subscript 2. The charges are separated by a distance of 25.0 centimeters. Two points are marked at the dashed line. Point A is marked 10.0 centimeters to the left of charge q subscript 2, and point B is marked 10.0 centimeters to the left of charge q subscript 1.
