a. By calculating the average distance and average location of the charge, then the field from the average charge.
b. By calculating the field from each charge and averaging their magnitude.
c. By calculating the field from each charge and averaging the vectors giving each field.
d. Calculate the field from each charge separately then add their magnitudes.
e. Calculate the field from each charge separately then add these contributions as vectors.

A steel pipe column (E 5 190 GPa, ? 5 14 3 1026/°C, d2 5 82 mm, and d1 = 70 mm) of length L 5 4.25 m is subjected to a temperature increase DT. The column is pinned at the top and fixed at the bottom. The tem- perature increase at which the column will buckle is approximately:
(A) 36 8C
(B) 42 8C
(C) 54 8C
