How to calculate the initial velocity needed for three or more masses to orbit each other?
Lets say I have one planet of mass $m_A$ and another of mass $m_B$. Lets say the distance between each of them is $r$.
How would I calculate the initial velocity needed for each in order to make the …

RC time constant in parallel circuit [closed]
$R_1 = 50k \Omega $
$ R_2 = 100k \Omega $
$ \mathcal{E} = 10V $
$ C = 10 \mu F $
So I want to find the $\tau$ time constant of this circuit after the switch is closed.
The only issue is that w …
