73. On the one hand, the conclusion (that Q= +1.00 µC) is clear from symmetry. If a more in-depth justification is desired, one should use Eq. 22-3 for the electric field magnitudes of the three charges (each at the same distance ra=3from C) and then find field components along suitably chosen axes, requiring each component-sum to be
