defence exam Agniveer Vayu Group X & XY Mock Test 01/2026 Physics Electric Fields and Gauss' Law Applications of Gauss’s Law
If there are only one type of charge in the universe, then
(\(\vec E\) → Electric field, \(\overrightarrow {ds}\) → Area vector)1
\(\oint \vec E \cdot \overrightarrow {ds} \ne 0\) on any surface
2
\(\oint \vec E \cdot \overrightarrow {ds}\) could not be defined
3
\(\oint \vec E \cdot \overrightarrow {ds}\) = ∞ if charge is inside
4
\(\oint \vec E \cdot \overrightarrow {ds}\) = 0 if charge is outside, \(= \frac{q}{{{\epsilon_0}}}\) if charge is inside
