$q_1 +\hspace{0.17em}{q}_2 = q_1\text{'} + q_2\text{'}$

$$\begin{gathered} x^2 -(q_1 + q_2)x + q_1{q}_2 = 0 \\ \Rightarrow \left\{\begin{array}{l}{x}_1 = a\\ x_2 = b\end{array}\right. \\ \Rightarrow \left\{\begin{array}{l}{q}_1 = a\\ q_2 = b\end{array}\right.hoặc \left\{\begin{array}{l}{q}_1 = b\\ q_2 = a\end{array}\right. \end{gathered}$$

$\mathit{q}\mathbf{ }\mathbf{=}\mathbf{ }\mathbf{\pm }\mathit{n}\mathit{e}$

$\left\{\begin{array}{l}\frac{r_{13}}{r_{23}}=\sqrt{\frac{m_1}{m_2}}\\ r_{13} + r_{23} = AB\end{array}\right.$

$k_0{l}_0 = k_1{l}_1 = ... = k_n.l_n= E.S$

$Q = mq$

$$\begin{gathered} A = F.∆s \\ \Rightarrow A = p.S.∆s \\ \Rightarrow A = p.∆V \\ \Rightarrow A = p.(V_2 - V_1) \end{gathered}$$

$W_2-W_1=A_{12}=A_{F_{ms}}$

$H =\frac{A_{ci}}{A_{tp}}=\frac{P_{ci}}{P_{tp}}$

$v^2 = 2gS$
