A) \[A\]
B) \[B\]
C) \[C\]
D) \[D\]
Correct Answer: B
Solution :
The body is describing a vertical circle, \[\therefore \] \[T-mg\cos \theta =\frac{m{{v}^{2}}}{l}\] or \[T=mg\cos \theta +\frac{m{{v}^{2}}}{l}\] Tension is maximum when \[\cos \theta =+1\] and velocity is maximum. Both condition are satisfied at\[\theta ={{0}^{o}}\](ie, at lowest point\[B\]).You need to login to perform this action.
