A student is revising the fundamental facts about electrostatic interaction between two point charges kept in vacuum.
(i) State Coulomb’s law in words.
(ii) Write the mathematical expression for the magnitude of the electrostatic force between two point charges separated by a distance r in vacuum, clearly explaining each symbol used.
(iii) Give the SI unit and dimensional formula of electric charge.
