$($b$)$

A spherical Gaussian surface surrounds a point charge q$.$ Describe what happens to the net flux through the surface if:$-$

$$

$$

$$ i$.$ the charge is halved?

$$

$$ ii$.$ the volume of the sphere is halved?

$($c$)$

What is the net flux through the surface if the charge q is a neutral charge?
