Question

The electric flux through a spherical surface is 1.4 ✕ 105 N · m2/C. What is the net charge (in C) enclosed by the surface?

Answer 1

Answer:

The  value is   $Q_{net} =  1.239 *10^{-6} \  C$

Explanation:

From the question we are told that

   The electric flux is $\Phi =  1.4*10^{5} \  N\cdot m^2/C$

     

Generally the net charge is mathematically represented as

    $Q_{net} =  \Phi *  \epsilon_o$

Here $\epsilon_o$ is the permetivity of free space with value  

       $\epsilon_o =  8.85*10^{-12}  \  \  m^{-3} \cdot kg^{-1}\cdot  s^4 \cdot A^2$

So

   $Q_{net} =  1.4*10^5 *  8.85*10^{-12}$

=>   $Q_{net} =  1.239 *10^{-6} \  C$
