(c) actual transfer of electrons. Charging occurs due to the transfer of electrons between objects, either by contact or induction. Protons are fixed within the nucleus, and neutrons do not participate in the process of charging. Class 12th Science Physics ...
The correct answer is (a) no net charge is enclosed by the surface. According to Gauss’s law, the net electric flux through a closed surface is proportional to the total charge enclosed. If the flux is zero, the total enclosed ...
(a) spheres. At a large distance, a collection of charges with a nonzero net charge behaves like a point charge, producing spherical equipotential surfaces centered around the effective charge distribution. Class 12th Science Physics NCERT MCQ Questions NCERT Books MCQ ...
(d) Zero. On the equatorial line of an electric dipole, the potential at any point is always zero because the contributions from the positive and negative charges cancel out, resulting in no net electric potential. Class 12th Science Physics NCERT ...
