I need someone to help me find the correct value for Qe. The one I have is incorrect. I don't know what formula's to use. My instructions for the next part: Clearly show your calculations using the proper variable terminology. Include the calculation of percentage error for your value of the charge on a pitch ball.

Table 1 Charge on a Pith Ball (you may not actually need all of these values) k = 9.0x109 N m2/C2 mass of a pith ball (from lab info box), m = OXID kg charge # = 120 -9 accepted value for charge on one pith ball (info box), Qa = 15x10 c experimental value for charge on one pith ball, Qe = 8 2ex c separation between centers of pith balls, r= 0 08 m 8cm length of the pendulum, L = _D. 20 m deflection angle of a pith ball from the vertical, 0 = _ (Q.0
