1
Coulombs Law in 2D Lesson 3

2
Objectives determine, quantitatively, the magnitude and direction of the electric force on a point charge due to two or more other point charges in a plane.

3
Review ex) Two equally charged pith balls are 3.0 cm apart in air and repel each other with a force of 4.0 x 10 -5 N. Find the charge on each ball.

6
Vector Nature of Coulomb's Law The electric force is a vector, which means it can be added, subtracted or broken into x and y components like any other vector. Mind your negative signs (for direction only!!!)

7
Note: Enter the test charge! A test charge is an imaginary object of set charge and negligible mass. It is used to determine the direction of the electric force at a particular position. This is probably not what it looks like...

8
Example: A test charge Q 2 (q = 2.0 μC) is placed halfway between a charge Q 1 = 6.0 μC and a charge Q 3 = 4.0 μC which are 10 cm apart. Find the force on Q 2 and its direction. Step 1: Determine each electric force. Step 2: Determine the total force on the testy.

9
Example Find the force on the 3rd charge:

10
Example Find the force on the 2nd charge:

11
Example Find the net force acting on the test charge.
