Please show all work done to solve the problem, handwritten answers preferred, thank you
An external, uniform electric field of magnitude 6.00 x 103 N/C points 30 degree to the right of downward, as shown below (assume the electric field vector lies in the plane of the page, parallel to the front and back of the box). An empty, closed shoebox has a top and bottom that are 35.0 cm by 25.0 cm, vertical sides that are 25.0 cm by 20.0 cm, and a front and back that are 20.0 by 35.0 cm. The box contains no electric charge. Important Note: For this problem, count electric flux as positive if the electric field lines are exiting the box, and negative if they are entering the box. Calculate the electric flux through each of the six sides of the box.Explanation / Answer
through top face, flux = - 6000 * 35*25 / 10^4 * cos30
= -454.7 Nm^2 /C
through bottom face, flux = + 66000 * 35*25 / 10^4 * cos30
= +454.7 Nm^2 /C
through front face, flux= 0
though rear face, flux = 0
through visible side face, flux = + 6000 * 25 *20 /10^4 * cos60
= +150 Nm^2 /C
through invisible side face, flux = - 6000 * 25 *20 /10^4 * cos60
= -150 Nm^2 /C
