Laws Of Motion Question 156
Question: Three solids of masses $ m _{1},m _{2} $ and $ m _{3} $ are connected with weightless string in succession and are placed on a frictionless table. If the mass $ m _{3} $ is dragged with a force T, the tension in the string between $ m _{2} $ and $ m _{3} $ is [MP PET 1995]
Options:
A)$ \frac{m _{2}}{m _{1}+m _{2}+m _{3}}T $
B) $ \frac{m _{3}}{m _{1}+m _{2}+m _{3}}T $
C) $ \frac{m _{1}+m _{2}}{m _{1}+m _{2}+m _{3}}T $
D) $ \frac{m _{2}+m _{3}}{m _{1}+m _{2}+m _{3}}T $
Show Answer
Answer:
Correct Answer: C
Solution:
$ T’=(m _{1}+m _{2})\times \frac{T}{m _{1}+m _{2}+m _{3}} $
