A) \[\frac{8}{7}F\]
B) \[\frac{1}{7}F\]
C) \[\frac{1}{8}F\]
D) \[\frac{1}{5}F\]
E) \[\frac{7}{8}F\]
Correct Answer: E
Solution :
Acceleration of the system \[a=\frac{F}{\left( m+\frac{m}{3} \right)}\] \[\therefore \]Tension in the middle of the rope \[t=\left( M+\frac{M}{6} \right)a\] Or \[T=\frac{7m}{6}.\frac{3F}{4m}\] Or \[T=\frac{7}{8}F\]You need to login to perform this action.
