Introduction to Coulomb's Law or the Electric Force (12:10)
Coulomb’s Law is introduced and compared to Newton’s Universal Law of Gravitation. “Point Charge” is defined. Micro, Nano, and Pico prefixes are explained. Two basic example problems are solved. And a the fact that the electric force is typically much larger than the gravitational force is shown. This is an AP Physics 1/JEE/NEET Topic.
