Answer 2

The electric potential increases.

• There is a uniform electric field, where the negative charge is in motion in the x-direction.
• This tells us that, the negative charge is moving in a positive direction which requires an external force to be applied.
• Hence the negative charge would require more electric potential or energy to be applied in order to move the charge.
• So the electric potential increases.
