Question

Total flux phi comes out of a sphere of radius r.keeping amount of charge constant,if the radius is made 2r how much flux will come out of sphere now

Answer 1

By gauss's Law we know that,

Φ = q / ε0

As we can see from formula that flux does not depend upon the distance Hence, Flux will remain constant.

Therefore, Flux Φ will come out sphere of radius 2r.
