Calculate the flux of the indicated electric field vector through the surface. (E = 130, = 66.0°.)
I know the differential equation for flux d[tex]\phi[/tex]= A [tex]\bullet[/tex] d S
[/B]
My textbook told me that "if there is zero total charge within the closed surface S, there is no net flux of the electric field vector through S."
I guessed that the total flux was 0, but that was wrong...
Or maybe it's
[tex]\int[/tex] (from O to .05m) <130,0> [tex]\bullet[/tex] [tex]\pi[/tex] r ^2(<cos60,sin60>)
But I'm not really even sure how to do an integral with a dot product(would you dot them first?), and I'm fairly certain that's wrong...
Any ideas?
