Question

Two particles of equal masses are revolving in circular paths of radii r₁ and r₂ respectively with the same period. The ratio of their centripetal force is(a) $\frac{r_{1}}{r_{2}}$ (b) $\sqrt{\frac{r_{2}}{r_{1}}}$(c) $(\frac{r_{1}}{r_{2}})^{2}$ (d) $(\frac{r_{2}}{r_{1}})^{2}$

Answer 1

I think the answer should be part c
