A disk is undergoing pure rolling motion with speed $v$. The radius of the disk being $R$ and mass being $m$. Then the angular momentum of the disk about the bottom most point will be having magnitude equal to

A disk is undergoing pure rolling motion with speed $v$. The radius of the disk being $R$ and mass being $m$. Then the angular momentum of the disk about the top most point will be having magnitude equal to

A rod of mass $m$ and length $2R$ is fixed along the diameter of the ring of same mass $m$ and radius $R$ as shown in figure. The combined body is rolling without slipping along $x$-axis. Then the angular momentum about $z$-axis is having magnitude equal to

A particle of mass $m$ is thrown at angle $\alpha$ with the vertical, with initial velocity $u$, under gravity. The angular momentum of particle about point of projection when at highest point will be

A small ball of mass $m$ tied to a string is whirled around in a horizontal circle. The length of the string is gradually decreased by pulling it as shown. If $r$ is the radius of the circular path at any instant, the tension will be proportional to
