Consider a system of three charges shown in (Figure 1). An object with charge q4 = +7.0×10−9C is moved to position C from infinity (not shown in the figure). q1 = q2 = q3 = +10.0×10−8C. Determine the work done on the system by moving the charge q4 from infinity to point C, but for
q1 = q3 = -10.0×10−9C and q2 = +10.0×10−9C.
