SUMMARY
This discussion focuses on applying Gauss's Law to determine the electric field of a charged sphere. For a radius \( r < 1 \), the electric field \( E \) is calculated using the formula \( E = \frac{\rho r}{3 \epsilon_{0} \epsilon_{r}} \), where \( \rho \) is the charge density. The confusion arises regarding the behavior of the electric field for \( r > 1 \), where the charge density is zero, indicating that the electric field should also be zero in that region. The key takeaway is that outside the charged sphere, the electric field does not exist due to the absence of enclosed charge.
