A charge of 25 nC is uniformly distributed along a circular arc (radius = 2.0 m) that is subtended by a 90-degree angle. What is the magnitude of the electric field at the center of the circle along which the arc lies?
 a. 81 N/C
  b. 61 N/C
  c. 71 N/C
  d. 51 N/C
  e. 25 N/C

Question 2

 a. 81 N/C
  b. 74 N/C
  c. 61 N/C
  d. 88 N/C
  e. 20 N/C
