Question

A point charge of −3μC is locatedat the center of a sphere with a radius r=5cm. What is the net electric flux through the surface?short answer pls asap

Answer 1

Given:

The total charge enclosed by the surface of the sphere, q=-3 μC

The radius of the sphere, r=5 cm=5×10⁻² m

To find:

The net electric flux through the surface of the sphere.

Step-by-step explanation:

From Gauss's law, the net electric flux through the surface of the sphere is given by,

`\phi=(Q)/(\epsilon_0)`

Where ε₀ is the permittivity of free space.

On substituting the known values,

`\begin{gathered} \phi=-(3*10^(-6))/(8.85*10^(-12)) \\ =339*10^3\text{ Nm}^2\text{/C} \end{gathered}`

Final answer:

The net flux through the surface of the sphere is 339×10³ Nm²/C
