A) \[\frac{21}{8}g,\,\frac{g}{8}\]
B) \[\frac{12g}{5},\,\frac{g}{5}\]
C) \[\frac{21g}{8},\,\frac{g}{5}\]
D) \[\frac{7g}{8},\,\frac{g}{8}\]
Correct Answer: B
Solution :
Tension in the string,\[T=\frac{2{{m}_{1}}{{m}_{2}}}{{{m}_{1}}+{{m}_{2}}}g\] \[=\frac{2\times 2\times 3}{2+3}g=\frac{12}{5}g\]and acceleration \[a=\left( \frac{{{m}_{2}}-{{m}_{1}}}{{{m}_{1}}+{{m}_{2}}} \right)g=\left( \frac{3-2}{3+2} \right)g=\frac{g}{5}\]
