Question

Find the electric flux through the closed surface S, in the following diagram. S
+2 nc • 1 nc -1 nc​

Answer 1

sorry I don't know the answer I am very sorry

Answer 2

According to the Gauss Law

• Any closed surface surrounding a net charge q has an electric flux given by $\frac{q}{\epsilon}$

where q = total charge enclosed by the closed surface.

ε=8.85 ×10⁻¹²

The electric flux is independent of the shape of the surface.

In the given figure the total charge enclosed by the figure is

+2 nC + (-1nC) = 2 nC -1nC = 1 nC

The net charge enclosed(q) = 1 nC

The electric flux = $\frac{q}{\epsilon}$

= $\frac{10^{-9} }{8.85*10^{-12} }$

= 112 N/C m²
