Explanation / Answer

(a) Find the electric field at r = 1.00 cm from thecenter of this charge configuration.(MN/C)
      = 0.0    (always 0 insideconductor)

(b) Find theelectric field at r = 3.00 cm from the center of thischarge configuration. (MN/C)
      = k*Q/r^2 = (8.988e+9)*(17.0e-6)/(3.00e-2)^2 = 169.8 MN/C

(c) Find theelectric field at r = 4.50 cm from the center of thischarge configuration. (MN/C)
      = 0.0    (always 0 insideconductor)

(d) Find theelectric field at r = 7.00 cm from the center of thischarge configuration. (MN/C)
