Remove the positive charge by dragging it back to the box at the bottom, and drag a negative charge (blue) toward the middle of the screen.
determine how the electric field is different from that of the positive charge.
what statement best describes the differences in the electric field due to a negative charge as compared to a positive charge?

the Voltages become negative instead of positive but the magnitude remains the same.

Explanation:

If we remove  the positive charge by dragging it back to the box at the bottom, and drag a negative charge (blue) toward the middle of the screen, the Voltages become negative instead of positive but the magnitude remains the same.

i guess it’s a and b

thermal energy is the answer
