Two uniform rods, each of length 2.0 m, are bent to form semicircles. One rod has a charger per unit lent of 1.5 nC/m, and the other has a charge per unit length of 1.5 nC/m. The semicircles are joined to make a circle. What is the magnitude of the electric field at the center of the circle?
 a. 42 N/C
  b. 84 N/C
  c. 34 N/C
  d. 68 N/C
  e. 0

Question 2

A charge of 50 nC is uniformly distributed along the y axis from y = 3.0 m to y = 5.0 m. What is the magnitude of the electric field at the origin?
 a. 18 N/C
  b. 50 N/C
  c. 30 N/C
  d. 15 N/C
  e. 90 N/C
