JEE MainPhysicsElectrostaticsNumerical+4 / −1
The volume charge density of a sphere of radius 6 m6 \mathrm{~m}6 m is 2 μC cm−32 \,\mu \mathrm{C} \,\mathrm{cm}^{-3}2μCcm−3. The number of lines of force per unit surface area coming out from the surface of the sphere is ‾×1010 NC−1\underline{\hspace{2cm}}\times 10^{10} \,\mathrm{NC}^{-1}​×1010NC−1. [Given : Permittivity of vacuum ϵ0=8.85×10−12 C2  N−1−m−2\epsilon_{0}=8.85 \times 10^{-12} \,\mathrm{C}^{2}\, \mathrm{~N}^{-1}-\mathrm{m}^{-2}ϵ0​=8.85×10−12C2 N−1−m−2 )
