A) \[0.2\text{ }m/{{s}^{2}}\]
B) \[9.8m/{{s}^{2}}\]
C) \[5m/{{s}^{2}}\]
D) \[4.8\text{ }m/{{s}^{2}}\]
Correct Answer: A
Solution :
On releasing the motion of the system will be according to figure \[{{m}_{1}}g-T={{m}_{1}}a\] \[T-{{m}_{2}}g={{m}_{2}}a\] \[a=\left( \frac{{{m}_{1}}-{{m}_{2}}}{{{m}_{1}}+{{m}_{2}}} \right)g\] \[a=\left( \frac{5-48}{5+4.8} \right)\times 9.8\] \[=\frac{0.2}{9.8}\times 9.8=0.2\,m/{{s}^{2}}\]You need to login to perform this action.
