A) \[4\eta {{r}^{2}}T\]
B) \[2\eta {{r}^{2}}T\]
C) \[{{2}^{8/3}}\eta {{r}^{2}}T\]
D) \[{{2}^{5/3}}\eta {{r}^{2}}T\]
Correct Answer: C
Solution :
\[2.\frac{4}{3}\pi {{r}^{3}}=\frac{4}{3}\pi {{R}^{3}}\] \[R={{2}^{1/3}}r\] \[S.E.=T.4\pi {{R}^{2}}\] \[T4\pi {{2}^{2/3}}{{r}^{2}}\] \[T{{.2}^{8/3}}\pi {{r}^{2}}.\]You need to login to perform this action.
