The magnitude of the electric force between the two point charges is 4.15 * 10^-3 N
What is Coulomb's law?
The term Coulomb's law is used to calculate the magnitude of electric force between two point charges.
Given that;
q1= 33.7 nC
q2 = 21.9 nC
r = 40 mm (From the graph)
F = 9.0 * 10^9 * 33.7 * 10^-9 * 21.9 * 10^-9/(40 * 10^-3)^2
F = 4.15 * 10^-3 N
