The drive chain in a bicycle is applying a torque of 0.850 N  m to the wheel of the bicycle. You can treat the wheel as a thin uniform hoop (or ring) with a mass of 0.750 kg and a radius of 33.0 cm. What is the angular acceleration of the wheel?
 
  A) 10.4 rad/s2
  B) 20.8 rad/s2
  C) 5.20 rad/s2
  D) 3.43 rad/s2
  E) 1.06 rad/s2

Question 2

A +5.0-C point charge is 12 cm from a -5.0-C point charge. What is the magnitude of the electric field they produce at the point on the line connecting them
 
  where their electric potential (relative to infinity) is zero? (k = 1/40 = 9.0  109 N  m2/C2)
  A) 0 N/C
  B) 12.5 MN/C
  C) 0.75 MN/C
  D) 25 MN/C
  E) 1.5 MN/C
