Question

Space between two concentric conducting spheres of radii a and $\mathrm{b}(\mathrm{b}>\mathrm{a})$ is filled with a medium of resistivity $\rho$. The resistance between the two spheres will be:

Select the correct option:

$\frac{\rho}{4 \pi}\left(\frac{1}{a}-\frac{1}{b}\right)$

$\frac{\rho}{2 \pi}\left(\frac{1}{a}-\frac{1}{b}\right)$

$\frac{\rho}{2 \pi}\left(\frac{1}{a}+\frac{1}{b}\right)$

$\frac{\rho}{4 \pi}\left(\frac{1}{a}+\frac{1}{b}\right)$

✓ Correct! Well done.
