Physics · Electrostatic Potential
हिन्दीWhat is the electrostatic potential at a distance \( r \) from a point charge \( Q \) located at the origin, assuming the potential at infinity to be zero?
Correct answer · Option 3
\( \frac{Q}{4\pi\varepsilon_0 r} \)
Explanation
By integrating the electric field from infinity to \( r \), the electrostatic potential of a point charge is given by \( V(r) = \frac{Q}{4\pi\varepsilon_0 r} \).
