What is the electric potential 16.0 cm from a 4.00 μc point charge?

the potential at a distance of 16 cm from the charge will be 225000 volt

Explanation:

We have given charge

Distance between the charge r = 16 cm = 0.16 m

Electric potential is given by , here K  is constant which value is

So potential

So the potential at a distance of 16 cm from the charge will be 225000 volt
