Question
A small mass $m$ is attached to a massless string whose other end is fixed at $P$ as shown in the figure. The mass is undergoing circular motion is the $x-y$ plane with centre at $O$ and constant angular speed $\omega$. If the angular momentum of the system, calculated about $O$ and $P$ are denoted by $\vec{L}_O$ and $\vec{L}_P$ respectively, then

A ball of mass $10\, kg$ moving with a velocity $10 \sqrt{3}\, ms ^{-1}$ along $X-$axis, hits another ball of mass $20\, kg$ which is at rest. After collision, the first ball comes to rest and the second one disintegrates into two equal pieces. One of the pieces starts moving along $Y-$ axis at a speed of $10\, m / s$. The second piece starts moving at a speed of $20\, m / s$ at an angle $\theta$ (degree) with respect to the $X-$axis. The configuration of pieces after collision is shown in the figure. The value of $\theta$ to the nearest integer is
