Electric potential at a point ‘P’ due to a point charge, does not depend on _______.
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → mass of the point charge
The potential of a point charge depends only on the charge, the distance from it and the permittivity of the medium around it.
\( \displaystyle V = \frac{1}{4\pi\varepsilon}\,\frac{q}{r} \)
The formula contains q (option 1), r (option 2) and \( \varepsilon \) (option 3), but no mass. Potential is electrical potential energy per unit charge, so the mass of the charged body plays no part in it.
NCERT (2026-27):
Potential Due to a Point Charge – “… This, by definition is the potential at P due to the charge Q
\( \displaystyle V(r) = \frac{1}{4\pi\varepsilon_0}\,\frac{Q}{r} \qquad (2.8) \)”
