1. A non-conducting spherical shell, with an inner radius of R1 and an outer radius of R2, has a non-uniform spreading through its volume and density. the distance r from the center of the shell and a constant k. (a) Find the net charge O of the shell. (b) Calculate the electric field E at a distance R from the center over the range 0 EREY. (c) Find the maximum E. 

2. Two small charged beads of charge q and mass are a ring of radius R. Bead 1 is fixed at a position and bead 2 can be moved along the ring. The angle between these two beads from the center of the ring is q. (a) Calculate the electric field of magnitude E at the position of Bead 2 as a function of q. (b) Calculate the force on Bead 2 in the direction along the ring and find the equilibrium position. (c) If Bead 2 oscillates near the equilibrium position, calculate the oscillation frequency.
