A) \[2.0\,\,m{{s}^{-2}}\]
B) \[2.5\,\,m{{s}^{-2}}\]
C) \[3.0\,\,m{{s}^{2}}\]
D) \[4.0\,\,m{{s}^{-2}}\]
Correct Answer: A
Solution :
The maximum weight which can be suspended with the rope without breaking it\[=30\,\,kg\,\,wt\]. \[=30\times 10=300\,\,N\] \[\therefore \] \[300\,\,N=mg+ma\] or \[ma=300-mg=300-25\times 10=50\,\,N\] or \[a=\frac{50}{m}=\frac{50}{25}=2.0\,\,m{{s}^{-2}}\]You need to login to perform this action.
