In static equilibrium, the potential difference between two points inside a solid piece of metal Group of answer choices is zero because metals block electric interactions. is zero because the electric field is zero inside the metal. is non-zero if the piece of metal is not spherical. is non-zero if there are charges on the surface of the metal. is non-zero for reasons not given above. is zero for reasons not given above.

it is zero because the electric gap is zero within the material

Explanation:

In a metal you have many free electrons, and fixed charges formed by nuclei and electrons that are not free; therefore the charge carriers are the free electrons, these have the same negative charge and due to the lectrostatic force they repel each other as far as possible without leaving the material, this implies that at two points there must be the same potential because otherwise there would be a net Caesarian force accumulating charge in a part that would be eliminated by the Coulomb force.

With this we can review the statements the strap is: it is zero because the electric gap is zero within the material
