A) \[{{T}_{1}}<2{{T}_{2}}\]
B) \[{{T}_{1}}={{T}_{2}}\]
C) \[{{T}_{1}}>{{T}_{2}}\]
D) \[{{T}_{1}}<{{T}_{2}}\]
Correct Answer: D
Solution :
At the lowest point A the tension in the string is \[{{T}_{1}}=\frac{mv_{1}^{2}}{r}+mg\] ?(i) At the highest point B the tension in the string is \[{{T}_{2}}=\frac{m{{v}^{2}}}{r}-mg\] ?(ii) Therefore, it is quite clear that the tension at the highest point on the circle, is less than that of the tension at the lowest point.You need to login to perform this action.
