A) \[\frac{F}{{{m}_{1}}}\]
B) \[\frac{F}{{{m}_{1}}+{{m}_{2}}}\]
C) \[\frac{F}{{{m}_{2}}+{{m}_{3}}}\]
D) \[\frac{F}{{{m}_{1}}+{{m}_{2}}+{{m}_{3}}}\]
Correct Answer: D
Solution :
The acceleration of mass\[{{m}_{3}}\]= common acceleration of the system \[=\frac{force\text{ }applied}{total\text{ }mass}\] \[=\frac{F}{{{m}_{1}}+{{m}_{2}}+{{m}_{3}}}\]
