Correct Answer - Option 1 : q/ϵ
o
CONCEPT:
Gauss's law:
- According to Gauss law, the total electric flux linked with a closed surface called Gaussian surface is \(\frac{1}{ϵ_o}\) the charge enclosed by the closed surface.
\(\Rightarrow ϕ=\frac{Q}{ϵ_o}\)
Where ϕ = electric flux linked with a closed surface, Q = total charge enclosed in the surface, and ϵo = permittivity
Important points:
- Gauss’s law is true for any closed surface, no matter what its shape or size.
- The charges may be located anywhere inside the surface.
EXPLANATION:
Gauss's law:
- According to Gauss law, the total electric flux linked with a closed surface called Gaussian surface is \(\frac{1}{ϵ_o}\) the charge enclosed by the closed surface.
- So if the total charge enclosed in a closed surface is q, then the total electric flux associated with it will be given as,
\(\Rightarrow ϕ=\frac{q}{ϵ_o}\)
- Hence, option 1 is correct.
