Answer:The change in potential energy is

Explanation:From the question we are told that

The magnitude of the uniform electric field is

The distance traveled by the electron is

Generally the force on this electron is mathematically represented as

Where F is the force and q is the charge on the electron which is a constant value of

Thus

Generally the work energy theorem can be mathematically represented as

Where W is the workdone on the electron by the Electric field and is the change in kinetic energy

Also workdone on the electron can also be represented as

Where considering that the movement of the electron is along the x-axis

So

substituting values

Now From the law of energy conservation

Where is the change in potential energy

Thus
