A) \[\frac{45}{142}\]
B) 1
C) \[\frac{65}{162}\]
D) \[\frac{85}{162}\]
Correct Answer: D
Solution :
\[V\rho g=mg\Rightarrow \rho =\sigma \] \[a=\frac{5R}{6}\] \[\rho \frac{2}{3}\pi {{R}^{3}}g=\sigma \left( \frac{4}{3}\pi {{R}^{3}}-\frac{4}{3} \right)g+2\pi RT\] \[\Rightarrow \,\,\frac{T}{{{R}^{2}}}=\frac{85}{162}\]You need to login to perform this action.
