5 9. None of the constant terms will result in a nonzero contribution to the flux (see Eq. 23-4 and Eq. 23-7), so we focus on the x dependent term only: E non-constant = ( 4.00 y 2 ) i ^ (in SI units) . The face of the cube located at y = 4.00 has area A = 4.00 m 2 (and it “faces” the +j ^ direction) and has a “contribution” to the flux equal to E non-constant A = ( 4)(4 2 )(4) = –256 (in SI units). The face of the cube located at

Unformatted text preview: y = 2.00 m has the same area A (and this one faces the j ^ direction) and a contribution to the flux: E non-constant A = ( 4)(2 2 )(4) = 64 (in SI units). Thus, the net flux is = 256 + 64 = 192 Nm/C 2 . According to Gausss law, we therefore have q enc = = 1.70 10 9 C ....
