As we have learned

Gauss's Law -

Total flux linked with a closed surface called Gaussian surface.

Formula:

\phi = \oint \vec{E}\cdot d\vec{s}=\frac{Q_{enc}}{\epsilon _{0}}

 

- wherein

No need to be a real physical surface.

Qenc - charge enclosed by closed surface.

 

 .it follows inverse square law

 


Option 1)

r^{-1}

Option 2)

r^{-2}

Option 3)

r^{-3}

Option 4)

r^{-4}

JEE Main high-scoring chapters and topics

Study 40% syllabus and score up to 100% marks in JEE

F=kQq÷r^-2

F~r^-2

Gauss law us applicable where force obeys inverse square law.

Therefore *option 2* is correct
