A) \[R/r\]
B) \[r/R\]
C) \[{{R}^{2}}/{{r}^{2}}\]
D) \[{{r}^{2}}/{{R}^{2}}\]
Correct Answer: A
Solution :
\[\frac{{{a}_{R}}}{{{a}_{r}}}=\frac{\omega _{R}^{2}\times R}{\omega _{r}^{2}\times r}=\frac{T_{r}^{2}}{T_{R}^{2}}\times \frac{R}{r}=\frac{R}{r}\] [As\[{{T}_{r}}={{T}_{R}}\]]You need to login to perform this action.
