Question

Concentric metallic hollow spheres of radii R and 4R hold charges $Q_1$ and $Q_2$ respectively. Given that surface charge densities of the concentric spheres are equal, the potential difference V(R) – V(4R) is

Select the correct option:

$\frac{3 Q_2}{4 \pi \varepsilon_0 R}$

$\frac{3 Q_1}{16 \pi \varepsilon_0 R}$

$\frac{Q_2}{4 \pi \varepsilon_0 R}$

$\frac{3 Q_1}{4 \pi \varepsilon_0 R}$

✓ Correct! Well done.
