    Answer:

    The potential will be Va/b

    Explanation:

    So Let sphere A charged Q to potential V.

    so, V= KQ/a. ….(1

    Thus, spherical shell B is connected to the sphere A by a wire, so all charge always reside on the outer surface.

    therefore, potential will be ,

    V ′ = KQ/b = Va/b… That is from …..(1), KQ=Va]
