A charged particle is held at the center of two concentric conducting spherical shells. Figure a shows a cross section. Figure b gives the net flux Φ through a Gaussian sphere centered on the particle, as a function of the radius r of the sphere. The scale of the vertical axis is set by Φs = 2.4 × 105 N•m2/C. What is the net charge (in Coulombs) of shell B?
heres the picture:
The Attempt at a Solution
Do i take the flux from each section and add them up?
Because in the tutor, it said that the net flux for a gaussian shell with radius r in between the radius of shell a and b was just the flux in between them and not the flux between them + the flux inside shell a
so im a little confused...
becaus i thot net flux was ALL the flux inside that radius r summed up
