A) \[1\times {{10}^{9}}{{m}^{2}}/s\]
B) \[5\times {{10}^{9}}{{m}^{2}}/s\]
C) \[5\times {{10}^{8}}{{m}^{2}}/s\]
D) \[4\times {{10}^{15}}{{m}^{2}}/s\]
Correct Answer: C
Solution :
\[\frac{dA}{dt}=\frac{L}{2m}\,\,\,\,\,\,=\frac{2\times {{10}^{12}}}{2\times 2000}=5\times {{10}^{8}}\,\,{{m}^{2}}/s\]You need to login to perform this action.
