PHY 102 Coulomb's law and Electric Fields Objective Question
Take CBT

Question

What is the definition of 1 electron volt (eV)?
Options
A The energy required to move one electron one meter.
B The work done in carrying a charge +<i>e</i> (coulombs) through a potential rise of exactly 1 volt.
Correct Answer
C The charge of one electron multiplied by one Coulomb.
D The potential difference across an electron.
Correct Answer

Option B is the correct answer.

Detailed Explanation

Page 12 states: '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).' It also provides the conversion 1 eV = 1.602 × 10-19 J.

Hint

The name 'electron volt' directly implies a relationship between the elementary charge and potential.
