A) \[~10\text{ }m/{{s}^{2}}\]
B) \[~25\text{ }m/{{s}^{2}}\]
C) \[~2.5\text{ }m/{{s}^{2}}\]
D) \[~5\text{ }m/{{s}^{2}}\]
Correct Answer: C
Solution :
Tension the string\[=m(g+a)=\]Breaking force \[\Rightarrow \]\[20(g+a)=25\times g\Rightarrow a=g/4=2.5\,m/{{s}^{2}}\]You need to login to perform this action.
