A) \[\frac{g}{3},g\]
B) \[~g,\text{ }g\]
C) \[\frac{g}{3},\frac{g}{3}\]
D) \[g,\frac{g}{3}\]
Correct Answer: A
Solution :
[a] Before cutting the string \[kx=T+3\text{ mg }...\text{(i)}\] \[\text{T=mg }...\text{(ii)}\] \[\Rightarrow \text{kx=4mg}\] After cutting the string \[T=0\] \[{{a}_{A}}=\frac{4mg-3mg}{3m}\] \[{{a}_{A}}=\frac{g}{3}\uparrow \text{ and }{{a}_{B}}=\frac{mg}{m}=g\downarrow \]You need to login to perform this action.
