MCQ
Two particles of identical mass are moving in circular orbits under a potential given by $V(r)=K r^{-n}$, where $K$ is a constant. If the radii of their orbits are $r_1 \cdot r_2$ and their speeds are $v_1 \cdot v_2$, respectively. Then,
- ✓$v_1^2 r_1^n=v_2^2 r_2^n$
- B$v_1^2 r_1^{-n}=v_2^2 r_2^{-n}$
- C$v_1^2 r_1=v_2^2 r_2$
- D$v_1^2 r_1^{2-n}=v_2^2 r_2^{2-n}$
