Problem: 1. A +3 nC charge is at x = 0 cm and a −1 nC charge is at x = 4 cm. At what point(s) along the x-axis is the electric potential zero? If there are none, write “None” and make sure to explain your reasoning2. A −7 nC charge is at x = −2 cm and a +1 nC charge is at x = 2 cm. At what point(s) along the x-axis is the electric potential zero? If there are none, write “None” and make sure to explain your reasoning.3. A 5 nC charge is at x = −3 cm and a −2 nC charge is at x = 0 cm. At what point(s) along the x-axis is the electric potential zero? If there are none, write “None” and make sure to explain your reasoning.
