Question

1)What’s the relationship between the electric potential on the surface of and inside the conductor when all charges are at rest? 2)Define electron volt. 3)If you know electric potential V as a function of coordinates (x, y, z), how would you calculate the electric field vector? 4)If the electric potential at a certain point is zero, does the electric field at that point have to be zero? Explain. 5)If the electric field at a certain point is zero, does the electric potential at that point have to be zero? Explain.

Explanation / Answer

1) Rlectric field E on the surface of the conductor is perpendicular to the surface whereas the field inside the surface of the conductor is zero since the potential inside is constant and E being the negative gradient of potential is zero.
