Question

The value of 1/4nƐo is​

Answer 1

4πϵ 1 is 9\times 10^9\ Nm^2/C^29×10 9 Nm 2 /C 2.

Explanation:

so that the electric field is the force per unit charge. Since the unit of force is the Newton (N), the unit of electric field is N/C, where C is the unit of electric charge, the Coulomb. k = 1/4πϵ0 = 9×109Nm2/C2 = 9×109kgm3/C2s2.
