Question

Consider the electric field given by ~E =(2xi-3j) N/C, where x isin units of meters.
Now suppose we have a rectangular volume, a distance c from the y -z plane, with two edges length a and the third length b. Theoutgoing flux through the right surface
is:
1. right = -2 a b (a + c) .
2. right = -2 (a + c) .
3. right = -[2 (a + c) - 3] a b .
4. right = 2 (a + c) .
5. right = -3 a b .
6. right = [2 (a + c) - 3] a b .
7. right = 2 a b .
8. right = 2 a b (a + c) .
9. right = -2 a b .
10. right = 3 a b .
