Question Detail
Question
The electron volt (eV) is defined as the work done in carrying a charge of +e (coulombs) through a potential rise of exactly what voltage?
Correct Answer
Option A is the correct answer.
Detailed Explanation
According to page 12, 'The work done in carrying a charge +e (coulombs) through a potential rise of exactly 1 volt is defined to be 1 electron volt (eV).'
Hint
The name 'electron volt' directly implies its definition in terms of a unit of potential.
