Answer:
Explanation:
According to Gauss's theorem , total flux coming out of a closed surface area is equal to 1/ε₀ times charge enclosed
This flux coming out of enclosed charge does not depend upon the shape of enclosing surface area . It only depends upon the charge enclosed .
It the present context , in both the case ie in case of donut or sphere , since amount of charge enclosed is same , flux coming out too will be same in both the case
Hence the required ratio = 1 : 1
