6. Two charges q and Q are fixed in place along the x axis. Q = +3.8 nC is at x = -2.0 cm and

unknown charge q is located at x = 2.0 cm. 2 significant figures

B. Sketch both the equipotential lines and the electric field for the system (you need to have at least 5 field lines for the smallest charge and 6 potential lines for each charge)
