Question

An electron moves to the right in an electric field which is directed to the right. Which statement is true about the physics during this motion?

a)The work done by the field is positive and the change in the potential energy of the field-electron system is positive.

b)The work done by the field is negative and the change in the potential energy of the field-electron system is positive.    

c) The work done by the field is positive and the change in the potential energy of the field-electron system is negative.

d)The work done by the field is negative and the change in the potential energy of the field-electron system is negative.

e)The work done by the field is positive and the change in the potential energy of the field-electron system is zero.

f)The work done by the field is negative and the change in the potential energy of the field-electron system is zero.

Explanation / Answer

e)The work done by the field is positive and the change in the potential energy of the field-electron system is zero.
