Coulomb’s Law

Coulomb’s LawThe force between two electric charges is directly proportional to the product of the magnitude of the charges (q1 and q2) and inversely proportional to the square of the distance (r) between them. So, according to the coulomb’s law: F α  or F = K  Where...

Electric Charge

There are two types of electric charges:     (i) Positive charges     (ii) Negative charges. To show that there are two types of electric charges, let’s do some experiments. Take two empty plastic bottles and rub them with wool. This makes them both negatively...
