Question 17

Define specific charge

Answer 17

The specific charge of a charged particle is defined as the ratio of its charge to its mass.

Question 18

What is the equation for specific charge?

Answer 18

specific charge = (charge/mass)

Where;
charge is in coulombs [C]
mass is in kilograms [kg]
specific charge is in coulombs per kilogram [C kg^-1]
