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 $
