Physics · JEE Advanced · NTA Exams — Rotational Motion
Two particle of equal masses are revolving in circular paths of radii r1 and r2 respectively with the same speed. The ratio of their centripetal forces is :
- \(\frac{r_{2}}{r_{1}}\)
- \(\sqrt{\frac{\mathrm{r}_{2}}{\mathrm{r}_{1}}}\)
- \[\left(\frac{r_{1}}{r_{2}}\right)^{2}\]
- \[\left(\frac{r_{2}}{r_{1}}\right)^{2}\]
Answer
(A) r_ 2 r_ 1
