A) \[\frac{{{T}_{0}}}{\sqrt{7}}\]
B) \[\sqrt{7}{{T}_{0}}\]
C) \[7\,\,{{T}_{0}}\]
D) \[7\sqrt{7}\,\,{{T}_{0}}\]
Correct Answer: D
Solution :
\[{{T}^{2}}\propto {{r}^{3}}\] law; \[T_{0}^{3}\propto {{R}^{3}}\] & \[T_{s}^{2}\propto {{(<7R)}^{3}};\] \[{{\left( \frac{{{T}_{s}}}{{{T}_{0}}} \right)}^{2}}={{7}^{3}};\] \[{{T}_{s}}=7\sqrt{7}{{T}_{0}}\]You need to login to perform this action.
