Laws Of Motion Question 307
Question: Three identical blocks of masses $ m=2kg $ are drawn by a force $ F=10.2N $ with an acceleration of $ 0.6m{{s}^{-2}} $ on a frictionless surface, then what is the tension (in N) in the string between the blocks B and C?
Options:
A) 92
B) 3.4
C) 4
D) 9.8
Show Answer
Answer:
Correct Answer: B
Solution:
[b] $ F=( m+m+m )\times a $
$ \therefore a=\frac{10.2}{6}m/s^{2} $
$ \therefore T _{2}=ma=2\times \frac{10.2}{6}=3.4N $
