Laws Of Motion Question 162
Question: Two masses $ m _{1} $ and $ m _{2} $ are attached to a string which passes over a frictionless smooth pulley. When $ m _{1}=10kg, $
$ m _{2}=6kg, $ the acceleration of masses is [Orissa JEE 2002]
Options:
A) 20 $ m/s^{2} $
B) $ 5m/s^{2} $
C) 2.5 $ m/s^{2} $
D) $ 10m/s^{2} $
Show Answer
Answer:
Correct Answer: C
Solution:
$ a=( \frac{m _{2}-m _{1}}{m _{1}+m _{2}} )g=( \frac{10-6}{10+6} )\times 10=2.5m/s^{2} $
