A) \[3.27\,m/{{s}^{2}},\,6.54\,N\]
B) \[4.38\,m/{{s}^{2}},\,6.54\,N\]
C) \[3.27\,m/{{s}^{2}},\,9.86\,N\]
D) \[4.38\,m/{{s}^{2}},\,9.86\,N\]
Correct Answer: A
Solution :
Acceleration\[=\frac{{{m}_{2}}}{{{m}_{1}}+{{m}_{2}}}\times g\] \[=\frac{1}{2+1}\times 9.8=3.27\ m/{{s}^{2}}\] and \[T={{m}_{1}}a=2\times 3.27=6.54\ N\]
