Question

Two charges are placed on the x-axis. One has a charge of 30μC and is placed at x=0m; the other has a charge of -85μC and is placed at x=1m.

a) What is the x-coordinate of the place where the electric field is zero?

b)Where is the electric potential from these two charges zero? Select all that apply.

To the left of the 30μC charge.

Between the charges but closer to the 30μC charge.

Exactly halfway between the charges.

Between the charges but closer to the -85μC charge.

To the right of the -85μC charge.

Nowhere. The electric field from these two charges is never zero.
