Hello guys,

Here is a question from my Physics HW. Please answer the question fully including the sub-questions as well. Remeber, the rule on this website is 1 question and up to 4 subparts. Also please make sure the answer correct. High rating will be included to the first and correct answers.

*NOTE* do not write in CURSIVE because I cannot read it. Sorry for being picky, thanks!

G. consider the Gaussian cube show below. The tube n Domposed of six equalsize faces Where L 1.00 m, The electric field lines are shown indicating their direction and strength an each of the six face 25.0 N/C 20.0 N/C. 35.0 N/C 20.0 N/C 20.0 N/C

Explanation / Answer

a)

Net electric flux = electric field(E)*A(area) for the whole surface

= (E*A) for all the 6 faces

= 20*1^2 + 20*1^2 + 20*1^2 - 35*1^2 - 25*1^2 + 15*1^2

= 15 Wb

b)

Net charge inside the cube = Flux*permittivity = 15*8.854*10^-12 = 1.33*10^-10 C

c)

If a charge would have been outside the volume, net electric flux would not have changed as the electric flux depends on the net charge inside the volume
