4 2 A small metal sphere S is supported by an insulating string as shown in Fig. 2.1. Fig. 2.1 (Not drawn to scale) Sphere S has a negative charge while sphere R has a positive charge. Sphere S has a weight of 5.0 x 10-4 N and the tension of the string is 4.0 x 10-4 N. (a) On Fig. 2.1 draw the electric field line
