The electric potential at a point 9 cm from it is closest toOn the equatorial plane of an electric dipole, the electric potential at any point isThe electric potential due to a short dipole at large distances falls off with distance r asIf a charge q is moved through a potential difference V, the work done by the external force isThe relation between electric field E and potential V along a direction r isWhich property does NOT necessarily hold for a charged conductor in electrostatic equilibrium?Two charges +q and −q are placed at distance 2a. The electric potential V at a point on the axis at distance rA hollow charged conductor encloses an empty cavity. The electric field inside the cavity isThe work required to assemble a system of two point charges q₁ and q₂ separated by distance r₁₂ from rest at iA charge Q = 4 × 10⁻⁷ C is at the origin.
