Me ajudemmmmmmm, preciso mt

Answer 1

$Q_A = \ Carga \ de \ A = Q\\ Q_B = \ Carga \ de \ B = -Q \\ Q_C = \ Carga \ de \ C = 0 \\ \\ 1) Q_{final} = \ \frac{Q_B + Q_C}{2}= \frac{-Q+0}{2} = \frac{-Q}{2} = Q'_B = Q'_C \\ \\ 2) Q_{final}= \ \frac{Q_A + Q'_C}{2} = \frac{Q+ \frac{-Q}{2}}{2} = \frac{Q}{4} = Q'_A = Q''_C$
$3) Q_{final} = \ \frac{Q'_A + Q'_B}{2} = \frac{ \frac{Q}{4} + \frac{-Q}{2}}{2} = \frac{-Q}{8} = Q''_A = Q''_B\\ \\ Q_A'' = \frac{-Q}{8}$
