Question

Write down the unit of F q r and the constant of proportionality

Answer 1

The unit of F (force) is the Newton (N), the unit of q (charge) is the Coulomb (C), and the unit of r (distance) is the meter (m). The constant of proportionality is the Coulomb's law constant, k = 8.99 x 10^9 Nm^2/C^2.
