Two concentric conducting spherical shells produce a radially outward electric field of magnitude 49,000 N/C at a point 4.10 m from the center of the shells. The outer surface of the larger shell has a radius of 3.75 m.
 
  If the inner shell contains an excess charge of -5.30 C, find the amount of charge on the outer surface of the larger shell. (k = 1/40 = 8.99  109 N  m2/C2)

Question 2

If an atom in a crystal is acted upon by a restoring force that is directly proportional to the distance of the atom from its equilibrium position in the crystal, then it is impossible for the atom to have zero kinetic energy.
