A) \[\frac{g(1-g\mu )}{9}\]
B) \[\frac{2g\mu }{3}\]
C) \[\frac{g(1-2\mu )}{3}\]
D) \[\frac{g(1-2\mu )}{2}\]
Correct Answer: C
Solution :
\[a=\frac{{{m}_{1}}g-\mu ({{m}_{2}}+{{m}_{3}})g}{{{m}_{1}}+{{m}_{2}}+{{m}_{3}}}=\frac{m[g-2\mu g]}{3m}\] \[=\frac{g}{3}[1-2\mu ]\]You need to login to perform this action.
