Laws Of Motion Question 316
Question: Two monkeys of masses 10 kg and 8 kg are moving along a vertical rope which is light and inextensible, the former climbing up with an acceleration of $ 2m/s^{2} $ while the latter coming down with a uniform velocity of $ 2m/s $ . Find the tension (in newtons).
Options:
A) 200 N
B) 150 N
C) 300 N
D) 100 N
Show Answer
Answer:
Correct Answer: A
Solution:
[a] $ T=T _{1}+T _{2}=m _{1}( g+a )+m _{2}g $
$ =10( 10+2 )+8( 10 )=120+80=200N $
