The figure below shows a spherical Gaussian surface of radius $$R$$. A very long thin rod passing through the center of the sphere has a uniform linear negative charge density $$??$$. A charge $$?q$$ is located inside the Gaussian surface. Located outside is another charge $$+q$$. What is the net electric flux through the Gaussian surface? A. $$\frac{?2?R?q}{{?}_o}$$ B. $$\frac{q}{{?}_o}$$ C. $$?\frac{2?R}{{?}_o}$$ D. $$\frac{?2?R+q}{{?}_o}$$ E. $$?\frac{q}{{?}_o}$$
