Lesson 18 (Electric Charge and Light) of Dianna's Intro Physics Class on Physics Girl. Never taken physics before? Want to learn the basics of physics? Need a review of AP Physics concepts before the exam? This course is for you!

Exercises in this video:
1. How many electrons are in 1 Coulomb of charge? How many protons?

2. What is the electromagnetic force between an electron and a proton that are separated by 1nm?

3. To compare, what would the force of gravity between the proton and the electron be?

4. An electron is in a constant electric field with a strength of 4.4x10^5N/C. What force is being exerted on that electron by the field?
