Physics - Electrostatics Question with Solution | TestHub

Radius of conducting sphere $\left(R_1\right)=10\mathrm{cm}$ charge on the conducting sphere $=10\mu \mathrm{C}$ and radius of uncharged sphere $\left(R_2\right)=20\mathrm{cm}$ For a spherical conductor, the density of charge is proportional to its radius. Therefore ratio of density of charges of the spheres will be $1:2$.
