QUESTION.. 8 Point charges B and C, carrying charges of 5 x 10-9 C and 3 x 10-9 C respectively, are situated a certain distance from another point charge A whose charge is unknown. Point charges B and C are also situated a certain distance from each other. The distance between point charge A and C is 20 mm. The diagram below illustrates the situation. N A 20 mm W S E B- 5 x 10-9 C 3 x 10-9 C The net electrostatic force (Fnet) exerted on point charge B by both point charges A and C is 1,01 x 10-3 N, 63,43° north of west. Calculate the magnitude and the sign of the charge that point charge A was carrying.​
