Three concentric spherical metallic shells $A, B$ and $C$ of radii $a, b$ and $c(a

Question

Three concentric spherical metallic shells $A, B$ and $C$ of radii $a, b$ and $c(a < b < c)$ have charge densities $\sigma,-\sigma$ and $\sigma$ respectively. The potential of $A, B$ and $C$ are

Aicharya · Accepted Answer

$\frac{Q_{A}}{4 \pi a^{2}}=\sigma$ $-\frac{Q_{B}}{4 \pi b^{2}}=-\sigma$ $-\frac{Q_{C}}{4 \pi c^{2}}=\sigma$ $V_{B}=\frac{Q_{A}}{4 \pi \varepsilon_{0} b}-\frac{Q_{B}}{4 \pi \varepsilon_{0} b}+\frac{Q_{C}}{4 \pi \varepsilon_{0} c}=\frac{1}{\varepsilon_{0}}\left(\frac{a^{2}}{b}-b+c\right)$ ,

Three concentric spherical metallic shells \(A, B\) and \(C\) of radii \(a, b\) and \(c(a < b < c)\) have…
