Question

One electronVolt is defined as:
Options
A the total energy of an electron which has been accelerated through 1V
B the potential energy of an electron which has been accelerated through 1V
C the electric energy of an electron which has been accelerated through 1V
D the kinetic energy of an single electron which has been accelerated through 1V
Correct Answer
Correct Answer

Option D is the correct answer.

Detailed Explanation

An electronVolt (eV) is a unit of energy, defined as the kinetic energy gained by a single electron (or proton, or any elementary charge carrier) when it is accelerated through an electric potential difference of one volt. This energy conversion is from electric potential energy to kinetic energy.

Hint

Recall the definition of the electronVolt unit and how it relates to acceleration in an electric field.
