Question

explain electrostatic force between two charges and write vector form of this force ( 5 marks)​

Answer 1

Answer:

Coulomb's law, or Coulomb's inverse-square law, is an experimental law of physics that quantifies the amount of force between two stationary, electrically charged particles. The electric force between charged bodies at rest is conventionally called electrostatic force or Coulomb force.

Vector form of Coulomb's Law →F12 F 12 → = Force on q1 due to q2 →F12=14πε0εrq1q2r221^r21 F 12 → = 1 4 π ε 0 ε r q 1 q 2 r 21 2 r ^ 21 →F12=–→F21 F 12 → = – F 21 → (∵ ^r12=–^r21 r ^ 12 = – r ^ 21 ) Or →F12+→F21=0 F 12 → + F 21 → = 0 This is known as Vector form of Coulomb's Law.
