Q4PhysicsUnit 11: Electrostatics
A ball of radius R carries a positive charge whose volume charge density depends only on the distance r from the ball's centre as: ρ=ρ0(1−rR)\rho=\rho_{0}\left(1-\frac{r}{R}\right) where ρ0\rho_{0} is constant. Assume ϵ\epsilon as the permittivity of the ball. Then the magnitude of the electric field as a function of the distance r outside the ball is given by :
