👉 In physics, a coulomb is defined as the electric charge of two point charges placed at the ends of a conductor. It is equal to the product of the magnitude of the charges and the inverse square of their separation distance. For example, if you have two point charges with a separation of 10 cm, then the coulomb between them would be: \[ \text{Charge} = q_1 = m_1 / (4πε₀r) \] where
