Exercise 1

Two point charges, Q1 = -37 uC and Q2 = 46 uC, are separated by a distance of 12 cm. The electric field at the point P is zero (Figure 1) .How many electrons make up a charge of -70.0 uC ? Express your answer using three significant figures. AEQ N = electrons21 X 12 cm Q2 PA person scuffing her feet on a wool rug on a dry day accumulates a net charge of -65 uC
