A non uniformly shaped conductor is charged then at it's sharpest point
Electric potential will be maximum
Electric field will be maximum
Charge density will be minimum
Electric potential will be minimum
Charges are placed on the vertices of a square as shown Let $\vec E$ be the electric field and $V$ the potential at the centre. If the charges on $A$ and $B$ are interchanged with those on $D$ and $C$ respectively, then
Two charges of $4\,\mu C$ each are placed at the corners $A$ and $B $ of an equilateral triangle of side length $0.2\, m $ in air. The electric potential at $C$ is $\left[ {\frac{1}{{4\pi {\varepsilon _0}}} = 9 \times {{10}^9}\,\frac{{N{\rm{ - }}{m^2}}}{{{C^2}}}} \right]$
Shows that how the electrostatic potential varies with $\mathrm{r}$ for a point charge.
If the electric potential of the inner metal sphere is $10$ $ volt$ $\&$ that of the outer shell is $5$ $volt$, then the potential at the centre will be ......$volt$
The ratio of electric potentials at the point $E$ to that at the point $F$ is
