Charge is distributed uniformly in some space. The net flux passing through the surface of an imaginary cube of side $a$ in the space is $ϕ$ . The net flux passing through the surface of an imaginary sphere of radius $a$ in the space will be

Options:

Answer:

Solution:

By Gauss's law, flux equals enclosed charge divided by $ε_{0}$ .

$ϕ = \frac{ρ a ^{3}}{ε _{0}}$

$ϕ_{2} = \frac{ρ \frac{4 π a ^{3}}{3}}{ε _{0}}$

$ϕ_{2} = \frac{4 π}{3} ϕ$
