Project 4:

Determining the electrostatic interacting forces between charged particles in free space

1 Content

Electrostatic interacting force of n charged particles acting on charged particle q0 is determined

by the superposition principle as follows





i i F

In which, Fiis the electrostatic force of particle i acting on particle q0 This force is determined

by Coulomb's law:

r

i

r

q q k

F  20 

With , k 9 10 9Nm2 /C2; r- the distance between the i-th point charge and the point charge q0 This project requires students to use Matlab to calculate the Fx and Fy components of the electrostatic force between point charges in the Oxy plane

2 Requirements

1) Students should have basic programming knowledge of MATLAB

2) Learn about symbolic calculation and graphical interpretation in MATLAB

3 Tasks

Write Matlab program to:

1) Enter the number of charged particles

2) Enter the coordinates and charge of each point charge in the Oxy plane

3) Use symbolic calculations to calculate the Fx and Fy components of the electrostatic force due

to the remaining charged particles on each charged particle

Note: Students can use other non-symbolic approaches

Submitting report has to contain text explaining the content of the program and the entire code verified to run properly in Matlab
