A) \[3.33\times {{10}^{-10}}J\]
B) \[13.34\times {{10}^{-10}}J\]
C) \[6.67\times {{10}^{-10}}J\]
D) \[6.67\times {{10}^{-9}}J\]
Correct Answer: C
Solution :
[c] Work done, \[W=\Delta U={{U}_{f}}-{{U}_{i}}=0-\left[ \frac{-GMm}{R} \right]\] \[W=\frac{6.67\times {{10}^{-11}}\times 100}{0.1}\times \frac{10}{1000}\] \[=6.67\times {{10}^{-10}}J\]You need to login to perform this action.
