Field Due to Point Charges
Demo 4.4:
Square with Two Pairs of Charges
Given:
Four point charges on the corners of a square, with Q
1
= Q
2
= 1C, and Q
3
= Q
4
= -1C, as shown.
In this demo, arrows are used to sketch the electric field pattern in the
x-y
plane.
to display the graphical and analytical solution.
Note: Color intensity is proportional to the strength of the Electric field.
