A) 250 N
B) 490 N
C) 980 N
D) 1960 N
Correct Answer: C
Solution :
When helicopter is rising upward the tension in the rope is given by \[T=m(g+a)\] (Where a is acceleration of helicopter by which it is rising) Given: Mass of the person m = 70 kg accelerations\[a=4m/{{s}^{2}},\,g=10m/{{s}^{2}}\] Now, putting the given values in Eq. (i), we have \[T=70\text{ (}10+4\text{)}=70\times 14=980\text{ }N\]You need to login to perform this action.
