A sphere `S_(1)` of radius `r_(1)` encloses a total charge Q. If there is another concentric sphere `S_(2)` of radius `r_(2) (gt r_(1))` and there be no additional charges between `S_(1) and S_(2)` find the ratio of electric flux through `S_(1) and S_(2)`,

Explanation

`:' phi = (q)/(in_(0))`
`:. (Q_(1))/(Q_(2)) = (q_(1))/(in_(0)) = (q_(1))/(in_(0)) xx (in_(0))/(q_(2)) = (q_(1))/(q_(2)) = (Q)/(Q) = 1 " " :. Phi_(1) : phi_(2) = 1 : 1`
