Question

n = What is the electric flux on the bottom face of the box? What is the electric flux on the top face of the box? What is the electric flux on the left face of the box? What is the electric flux on the right face of the box? What is the electric flux on the front face of the box? What is the electric flux on the back face of the box? How much charge is inside the box (amount and sign)? Qinside = C n on the bottom face of the box? E z = N/C. (For clarity, the electric field on the front and back faces has not been shown in the diagram.) What is the unit vector E 1 = N/C. On every other surface of the box (front, back, top, left end, right end) the electric field is found to be The electric field is measured at locations on every surface of a rectangular box oriented with its long side on the x-axis, as shown in the diagram. The width w of the box is 7 cm, the height h of the box is 3 cm, and the depth d of the box is 2 cm. On the bottom of the box the electric field is found to be

Explanation / Answer

I don't completely understand what you are looking for in part a. n hat could be either the normal vector or the polarization field.

to find the flux for parts b through g you use the eqaution

a is a vector because area is represented by a vector normal to the surface you are looking at. It normally points outside of the box.

for the final part you must balance the equation:

 

I hope this helps
