Integrated Concepts: A 0.005 kg charged insulating ball hangs in a uniform horizontal electric field on a 0.3 m long string having Tension (T) as shown in Figure below. Given the charge on the ball is 1 JC , find the Electric field (E). Tcose Isin e FE mg [Hint: System is in equlibrium. So, EFx = 0 & EFy = 0. Also, Electric force FE = qE] a. 9.89 x 10# N/C O b. 7.89 x 10 N/C O c. 8.89 x 10# N/C O d. 6.89 x 103 N/C
