A point charge (5.0 pC) is located at the center of a spherical surface (radius = 2.0 cm), and a charge of 3.0 pC is spread uniformly upon this surface. Determine the magnitude of the electric field 1.0 cm from the point charge.
 a. 0.72 kN/C
  b. 0.45 kN/C
  c. 0.63 kN/C
  d. 0.90 kN/C
  e. 0.18 kN/C

Question 2

A charge of 8.0 pC is distributed uniformly on a spherical surface (radius = 2.0 cm), and a second charge of -3.0 pC is distributed uniformly on a concentric spherical surface (radius = 4.0 cm). Determine the magnitude of the electric field 5.0 cm from the center of the two surfaces.
 a. 14 N/C
  b. 11 N/C
  c. 22 N/C
  d. 18 N/C
  e. 40 N/C
