Please help a girl who doesnt understand physics!!! Plz help me with this problem!! I'm totally lost. 1) Sketch the electric field lines both between and outside two concentric conducting spherical shells when a positive charge q1 is on the inner shell and negative charge -q2 is on the other one. Explain your diagrams using the concepts of flux and Gauss's law. Show the difference between the cases q1>q2, q1=q2 and q1<q2. I'm not sure quite how 2 sketch field lines. Please help me!! Thanx!!!
