A metal sphere of radius ' a ' carries a charge Q as shown in figure. It is surrounded, out to radius b, by linear dielectric material of permittivity ' ∈ '. Choose the correct statements-
  • a)
    The potential at the centre relative to infinity is given by
  • b)
    The electric field for a < r < b will be equal to the electric field for r > b.
  • c)
    The surface charge density for dielectric at the outer surface will be  at the outer surface.
  • d)
    The volume charge density for dielectric is given by (ρ) = 0
Correct answer is option 'C,D'. Can you explain this answer?
