An unknown charge is located on the screen along with three spherical shells (red, green, and blue)--you can only see the part of the sphere that is in the plane of the page. A test charge is also shown that measures the electric field (in N/C) at that point (position is given in meters).
Calculate the flux through each spherical shell. You can click-drag on the test charge to change its position. Start
red: 352 Nm2/C green: 352 Nm2/C and blue: 352 Nm2/C.
