A) \[mg\]
B) \[mg\left[ 1{{\left( \frac{a}{1} \right)}^{2}} \right]\]
C) \[mg{{\left[ 1+\frac{a}{2L} \right]}^{2}}\]
D) \[mg{{\left[ 1+\left( \frac{a}{L} \right) \right]}^{2}}\]
Correct Answer: B
Solution :
\[T-mg\cos \theta =\frac{m{{v}^{2}}}{L}\] T is maximum, when\[\theta =0\]You need to login to perform this action.
