A positive point charge is placed at the center of an imaginary spherical surface. As a result, there is some total electric flux outward through the surface. For each change listed, how would the total outward flux though the surface changeChanges:a. A negative charge is placed just outside the surface. b. The charge is moved off-center by an amount equal to half the radius of the spherical surface. c. A positive charge is placed just outside the surface. d. A negative charge is placed just inside the surface e. A positive charge is placed just inside the surface. f. The radius of the spherical surface is doubled Flux:1. The total flux increases 2. The total flux decreases 3. The total flux is unchanged
