Question

A point-charge of 1.8 uC is at the centre of a cubical
Gaussian surface of 55 cm side. Find the net electric
flux through the surface. Ans. 2.0 x 105 N-mºc-1. solve
​

Answer 1

Explanation:

We can use the following equation to figure out the net electric flux.

\Phi=\dfrac{q}{\epsilon_0}Φ=

ϵ

0

q

(Where \PhiΦ is the net flux, \epsilon_0ϵ

0

is permittivity of free space and qq is the charge enclosed)

\Phi=\dfrac{1.8\times10^{-6}}{8.85\times10^{-12}}Φ=

8.85×10

−12

1.8×10

\Phi=2.034\times10^{5}Φ=2.034×10
