Question

What are the factors affect the Electric forces between two charges and What is the relationship between each factor and the Electric force ?

Answer 1

Step-by-step explanation:

If the two charges are point charges - i.e., they don't have a size - the force between these charges depends on the

• Magnitude if each charge, q1 and q2

• Sign of each charge (+ or -)

• Distance between the charges, r

This is essentially Coulomb’s Law:

FE = (kq1q2)/r2

For collections of charges, you need to find the electric field E, and then use this fields to find a force on a small test charge q in the field. The test charge is always small to help you map the electric field, but not disturb it.
