Question 2

Two long conducting cylindrical shells are coaxial and have radii of 20 mm and 80 mm. The electric potential of the inner conductor, with respect to the outer conductor, is +600 V.
 
  An electron is released from rest at the surface of the outer conductor. What is the speed of the electron as it reaches the inner conductor? (e = 1.60  10-19 C, mel = 9.11  10-31 kg, k = 1/40 = 8.99  109 N  m2/C2 )
  A) 1.1  107 m/s
  B) 1.3  107 m/s
  C) 1.5  107 m/s
  D) 1.7  107 m/s
  E) 1.9  107 m/s
