A) \[{{T}_{1}}={{T}_{2}}\]
B) \[{{T}_{2}}>{{T}_{1}}\]
C) \[{{T}_{1}}>{{T}_{2}}\]
D) tension in the string always remains the same
Correct Answer: C
Solution :
Tension,\[T=\frac{m{{v}^{2}}}{r}+mg\cos \theta \] For,\[\theta ={{30}^{o}}\], \[{{T}_{1}}=\frac{m{{v}^{2}}}{r}+mg\cos {{30}^{o}}\] \[\theta ={{60}^{o}}\], \[{{T}_{2}}=\frac{m{{v}^{2}}}{r}+mg\cos {{60}^{o}}\] \[\therefore \] \[{{T}_{1}}>{{T}_{2}}\]You need to login to perform this action.
