Final answer:
For hollow, uncharged conducting spherical shells, there is no electric field either inside or outside the shells, due to the properties of conductors in electrostatic equilibrium.
Step-by-step explanation:
The question addresses the behavior of electric fields around hollow, uncharged conducting spherical shells. According to physics principles, for hollow conducting shells that are uncharged, there will be no electric field either inside or outside the shells. Applying Gauss's Law, which is a principle stating that the total electric flux out of a closed surface is equal to the charge enclosed divided by the permittivity of the vacuum, we can determine the behavior of electric fields in relation to these shells. Since there are no charges inside a hollow, uncharged spherical conductor, the electric field inside is zero. The same principle explains that if there are no charges on the conductor, there is no electric field outside of it either, as the net enclosed charge is zero.
Therefore, the correct answer is: d) No electric field, since the shells are uncharged and the electric field both inside and outside is zero due to the properties of a conductor at electrostatic equilibrium.
