Two particles of mass m and 2m separated by distance r are describing circular path under mutual gravitational force of attraction, such that speed of mass m is $v_{0}$ , then :-

Options:(select one or more)

Answer:

A, C

Solution:

About the COM: $r_{1} = \frac{2 r}{3}$ (mass m) and $r_{2} = \frac{r}{3}$ (mass 2m) - (A) correct.

$v_{2} = ω r_{2} = \frac{v _{0}}{r _{1}} r_{2} = \frac{v _{0}}{2}$ - (C) correct, (B) wrong.

Same angular speed gives equal time periods - (D) wrong.
