A) \[\frac{7g}{8};\,\frac{g}{8}\]
B) \[\frac{21g}{8};\,\frac{g}{8}\]
C) \[\frac{21g}{8};\,\frac{g}{5}\]
D) \[\frac{12g}{5};\,\frac{g}{5}\]
Correct Answer: D
Solution :
\[T=\frac{2{{m}_{1}}{{m}_{2}}}{{{m}_{1}}+{{m}_{2}}}g=\frac{2\times 2\times 3}{2+3}g=\frac{12}{5}g\] \[a=\left( \frac{{{m}_{2}}-{{m}_{1}}}{{{m}_{1}}+{{m}_{2}}} \right)\ g=\left( \frac{3-2}{3+2} \right)\ g=\frac{g}{5}\]You need to login to perform this action.
