In the figure, a ball of mass $m$ is tied with two strings of equal length as shown. If the rod is rotated with angular velocity $\omega$, then

A$T_1 > T_2$

B$T_2 > T_1$

C$T_1=T_2$

D$T_1=\frac{T_2}{6}$

Solution

(a)
For vertical equilibrium
$T_1 \cos \theta=m g+T_2 \cos \theta$
$T_1=\frac{m g}{\cos \theta}+T_2$
$\theta < 90^{\circ} \text { so } \cos \theta > 0$
$\Rightarrow T_1 > T_2$

A simple pendulum consisting of a mass $M$ attached to a string of length $L$ is released from rest at an angle $\alpha$. $A$ pin is located at a distance $l$ below the pivot point. When the pendulum swings down, the string hits the pin as shown in the figure. The maximum angle $\theta$ which string makes with the vertical after hitting the pin is :-
