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

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

=>   $Q_{net} = 1.239 *10^{-6} \ C$
