Three charges q = 7 nc, q2= -4 nC and q3= -3 nC are arranged as shown in the diagram below. P 3m m Im 1 A 1 J 92 Im B 2m 93 Determine the E-field and potential at the point A and point B as shown on the diagram. Determining the electric field at point A: Intermediate work: EAt A due to q1= EAt A due to q2 = N/C, 0= degrees N/C, 0 = degrees N/C, 0 = degrees EAt A due to q3 Net electric field at point A Enet at A = N/C, 0 = Determining the potential at point A: Intermediate work: V volts At A due to q1 V volts At A due to q2 VAt A due to q3 volts degrees
