A charged particle (q = -8.0 mC), which moves in a region where the only force acting on the particle is an electric force, is released from rest at point A. At point B the kinetic energy of the particle is equal to 4.8 J. What is the electric potential difference VB - VA?
 a. -0.60 kV
  b. +0.60 kV
  c. +0.80 kV
  d. -0.80 kV
  e. +0.48 kV

Question 2

A Geiger counter is like an electroscope that discharges whenever ions formed by a radioactive particle produce a conducting path. A typical Geiger counter consists of a thin conducting wire of radius 0.002 cm stretched along the axis of a conducting cylinder of radius 2.0 cm. The wire and the cylinder carry equal and opposites charges of 8.0  10-10 C all along their length of 10.0 cm. What is the magnitude of the electric field at the surface of the wire?
