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

To solve the problem, we need to find the ratio of electric flux through two concentric spheres, \( S_1 \) and \( S_2 \), where \( S_1 \) encloses a charge \( Q \) and \( S_2 \) is larger than \( S_1 \) with no additional charges in between.

### Step-by-Step Solution:

1. **Understanding Electric Flux**:
Electric flux (\( \Phi \)) through a closed surface is given by Gauss's law, which states:
\[
\Phi = \frac{Q_{\text{enc}}}{\epsilon_0}
