An irregular conductor carries a surface charge density of -6.75 C/m2 at and in the vicinity of a point P on the surface. An electron is released just above P outside the conductor.
 
  What are the magnitude and direction of its acceleration the instant after it is released? (0 = 8.85  10-12 C2/N  m2, e = 1.60  10-19 C, mel = 9.11  10-31 kg)

Question 2

A neutral hollow spherical conducting shell of inner radius 1.00 cm and outer radius 3.00 cm has a +2.00-C point charge placed at its center. Find the surface charge density
  (a) on the inner surface of the shell.
 
  (b) on the outer surface of the shell.
