There are two charged metallic spheres $S_{1}$ and $S_{2}$ of radii $R_{1}$ and $R_{2}$ respectively. The electric fields $E_{1}$ and $E_{2}$ on their surfaces are such that $E_{1} / E_{2} = R_{1} / R_{2}$ . Then the ratio $V_{1} / V_{2}$ of their electrostatic potentials on each sphere is

Options:

Answer:

Solution:

$\frac{E_{1}}{E_{2}} = \frac{R_{1}}{R_{2}} \frac{V_{1}}{V_{2}} = \frac{E_{1} R_{1}}{E_{2} R_{2}} = \frac{R_{1}}{R_{2}} \times \frac{R_{1}}{R_{2}} = {(\frac{R_{1}}{R_{2}})}^{2}$
