Answer to Question #217452 in Electricity and Magnetism for addie

Question

 What is the electric flux through a sphere of radius 1.5 m that carries a charge of

3 nC at its centre?           

Answer 1

radius=1.5m

$q=3nC=3\times10^{-9}C$

$\epsilon_0=8.85\times10^{-12} C^2/Nm^2$

Electric flux

$\phi =\frac{q}{\epsilon_0}$

$$\phi=\frac{3\times10^{-9}}{8.85\times10^{-12}}=338Nm^2/C$$
