KVPY SX SB Exam 05-Nov-2017 Question Paper

If coloumb's force ∝ $\frac{1}{{\mathit{r}}^3}$ gauss's law is not valid
∴ $\mathit{\varphi }\ne \frac{{\mathit{q}}_{\mathrm{en}}}{{\mathit{\epsilon }}_0}$
For static condition E = 0 in both of conductor
∴ ϕ through a Gaussian surface just under the surface of conductor = 0 but as
$\mathit{\varphi }=\frac{{\mathit{q}}_{\mathrm{en}}}{{\mathit{\epsilon }}_0}$ is not valid
So ${\mathit{q}}_{\mathrm{en}}=0$ is not correct statement. Some charge will present insider bulk of conductor.
