A) \[U=-1.92\times {{10}^{-4}}J\] and its value shall decrease if the sphere B is removed
B) \[U=-1.92\times {{10}^{-4}}J\] and its value shall increase if the sphere B is removed
C) \[U=-1.43\times {{10}^{-4}}J\] and its value shall decrease if mg is removed
D) \[U=-1.43\times {{10}^{-4}}J\] and its value shall increase if \[{{m}_{B}}\] is removed
Correct Answer: D
Solution :
\[U=-G\left[ \frac{{{m}_{A}}{{m}_{B}}}{{{r}_{AB}}}+\frac{{{m}_{B}}{{m}_{C}}}{{{r}_{BC}}}+\frac{{{m}_{C}}{{m}_{A}}}{{{r}_{CA}}} \right]\]You need to login to perform this action.
