| (i) lifted with an acceleration \[4.9\,m/{{s}^{2}}\] |
| (ii) lowered with an acceleration \[4.9\,m/{{s}^{2}}.\] |
| The ratio of the tension is |
A) 3 : 1
B) 1 : 3
C) 1 : 2
D) 2 : 1
Correct Answer: A
Solution :
[a] \[{{T}_{1}}=m(g+a);\]\[{{T}_{2}}=m(g-a)\]\[\Rightarrow \]\[\frac{{{T}_{1}}}{{{T}_{2}}}=3:1\]
