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 \[\theta =0{}^\circ \] (ie, at lowest point B).You need to login to perform this action.
