 Soient deux charges, $Q_1$, $Q_2$, de masse $m_1$, $m_2$, suspendues chacune à 
-une ficelle de longueur $l$ et formant un angle $\theta_1$ et $\theta_2$ avec 
-la verticale respectivement et se trouvant à l'équilibre.
+une ficelle de longueur $l$ et formant un angle $a_1$ et $a_2$ avec la 
+verticale respectivement et se trouvant à l'équilibre (voir @fig:pendulum).
 
-1. Si $Q_1=Q$ et $Q_2=2Q$ et $m_1=m_2=m$ déterminer $\theta_1/\theta_2$.
