I need some guidance if anyone can help me!(adsbygoogle = window.adsbygoogle || []).push({});

1. A small cube of volume 8.0 cm^3 is .30 cm from a metal sphere that has charge 2.00uC. If the cube is empty, what is the total flux through it?

I tried finding the flux of the sphere as if it was a point charge but I don't know where to go from there or even if there is right.

2. a) At a distance of .200 cm from the center of a charged conducting sphere with radius .100 cm, the electric field is 480 N/C. What is the electric field .600 cm from the center of the sphere?

b) At a distance of .200 cm from the axis of a very long charged conducting cylinder with radius .100 cm, the electric field is 480 N/C. What is the electric field .600 cm from the axis of the cylinder?

c) At a distance of .200 cm from a large uniform sheet of charge, the electric field is 480 N/C. What is the electric field 1.20 cm from the sheet?

Ok that's the second rather long question, so first I did a bunch of work for part a and now I'm thinking maybe I didn't have to do any work bc isn't the electric field the same outside of the object everywhere? I dunno though I'm all confused and TA's are not cool to teach physics with calculus. So if anyone can help me before tomorrow morning I'd love it...

Thanks all..
