SUMMARY
The electric flux through a sphere surrounding no charge is zero, as established by Gauss's Law. In this scenario, a point charge Q is located 2R above the center of a spherical surface with radius R, resulting in a net electric flux of zero through the sphere. However, to estimate the flux from charge Q that intersects the sphere, one must calculate the fraction of the total flux emitted by Q that passes through the sphere's surface. This involves determining the cross-sectional area of the sphere relative to the expanding area of the flux lines from charge Q.
