Homework Statement



A spherical shell of radius 4 m is placed in a uniform electric field with magnitude
7020 N/C. Determine the total electric flux through
the shell. Answer in units of N · m^2/C.

Homework Equations



Gauss's Law

The Attempt at a Solution



I thought this would be as simple as E * 4[tex]\pi[/tex]r[tex]^{2}[/tex] , but it's not working

I did 7020 * 4[tex]\pi[/tex]*4[tex]^{2}[/tex] and got 1411454.747, which isn't right. Is there something more to the problem that I'm missing?

Is there any charge enclosed inside the shell? If there is no charge inside the shell, and the only electric field of concern is caused by some sort of charge distribution outside the shell, what does Gauss' law say about that?
