    d Option is incorrect.. option b is also correct, because if we assume sphere around origin then flux is zero and potential is constant so it create equipotential surface around origin.

    according to me, ques no 32 is msq because option a is also correct. potential due to dipole is proportional to 1/(r^2)

    for ques 32, option c is right because dipole has +q,-q charge so total charge is zero, therefore electric flux is zero (electric flux=total charge enclosed/epsilon)
