How Does Charging Affect the Electric Field Inside a Metal Sphere?

[Iron_Man_123]

The electric field inside an uncharged metal sphere is initially zero.
If the sphere is the positively charged, the field at the center of the sphere will be...?

Metal is a conductor, so the charges are free to move wherever they want inside it. They will rearrange themselves to cancel out any field inside the sphere. So at equilibrium the electric field inside a conductor is zero

Does the answer change if the sphere is hollow?

Does the answer change if the sphere is hollow?

No it doesn't matter, The same thing will happen producing a zero electric field inside the hollow sphere
