Question

please explain why!!

1. An electron is released from rest in a region of space with a nonzero electric field. As the electron moves, does the electric potential energy of the system increase or decrease? Explain.

2. An electron is released from rest in a region of space with a nonzero electric field. As the electron moves, does the electron move from a position of high to low electric potential? Explain.

Answer 1

1)

The electron is released from rest in a region of space with an electric field .

Electron moves in opposite direction to electric field, from lower to higher potential.

Change in potential energy is

But Potential

That is electrical potential energy of the system is decreasing.

2)

As electron is negatively charged particle,

Force on the electron is

Direction of electron is in the opposite direction of electric field.

The direction of electric field is from higher to the lower potential.

That is electron moves from lower potential to higher potential.
