An electric dipole consisting of charges + q and - q separated by a distance r, is kept symmetrically at the centre of an imaginary sphere of radius R. Another point charge Q is also kept at the centre of the sphere. The net electric flux coming out of the sphere will be

(i) "The outward electric flux due to charge +Q is independent of the shape and size of the surface which encloses it." Give two reasons to justify this statement.
(ii) Two identical circular loops ′1′ and ′2′ of radius R each have linear charge The loops are placed coaxially with their centres R−3​ distance apart. Find the magnitude and direction of the net electric field at the centre of loop ′1′
