A) 2
B) 4
C) \[\frac{3}{4}\]
D) \[\frac{5}{4}\]
Correct Answer: A
Solution :
F. B. D of rope +4 kg block: \[{{T}_{A}}-8g=8a\] \[\Rightarrow \]\[{{T}_{A}}=8(a+g)\] (1) F. B. D of 4g. block: \[{{T}_{B}}-4g=4a\] \[\Rightarrow \]\[{{T}_{B}}=4(a+g)\] (2) Dividing equation (1) by (2), we get \[\frac{{{T}_{A}}}{{{T}_{B}}}=2\] Hence, the correction option is [a].You need to login to perform this action.
