CONCEPT:

Coulomb’s law: When two charged particles of charges q1 and q2 are separated by a distance r from each other then the electrostatic force between them is directly proportional to the multiplication of charges of two particles and inversely proportional to the square of the distance between them.

F1 J.K Madhu 03.04.20 D1

Force (F) ∝ q1 × q2

\(F \propto \frac{1}{{{r^2}}}\)

\(F = K\frac{{{q_1} \times {q_2}}}{{{r^2}}}\)

Where K is a constant = 9 × 109 Nm2/C2

EXPLANATION:

  • Coulomb’s Law talks about the magnitude of the attraction between the two charges.
  • It says that the force is directly proportional to the product of the quantity of the two charges and inversely proportional to the square of the distance between them.
