If a conducting sphere has a negative net charge and there is a positive point charge at the center of the sphere, what charge would you use to find the Electric Field at a point outside the sphere?(adsbygoogle = window.adsbygoogle || []).push({});

The equation is E=kq/r^2.

Would I use the net charge of the sphere, or do I need to calculate a new charge due to the positive one at the center?
