A horizontal disc is freely rotating about a vertical axis passing through its centre at the rate of `100rpm`. A bob of wax of mass `20g` falls on the disc and sticks to it a distance of `5cm` from the axis. If the moment of inertia of the disc about the given axis is `2xx10^(-4) kgm^2`, find new frequency of rotation of the disc.

A horizontal disc ratating about a vertical axis passing through its centre makes 180 rpm. A small piece of wax of mass 10 g falls vertically on the disc and stricks to it at a distance reduced to 150 rpm , calculate moment of inertia of the disc.

A horizontal disc is freely rotating about a vertcal axis passing through its centre at the rate of 125 r.p.m. A blob of wax of mass 50 gm falls on it and sticks to it at a distance of 10 cm from the axis. If the reslting frequency of rotation is 75 r.p.m, calculate the moment of inertia of the disc.

A unifrom horizontal disc is freely rotating about a vertical axis through its centre at the rate of 240 rpm. A blob of wax of mass 2 g falls on it and sticks to it at 25 cm from the axis. If the frequency of rotation of the disc is reduced by 60 rpm. calculate the moment of inertia of the disc. lt

Obtain an expression for potential energy of a particle performing simple harmonic motion. Hence evaluate the potenhtial energy (a) at mean position and (b) extreme position. A horizontal disc is freely rotating about a transverse axit passing through its centre at the rate of 100 revolutions per minute. A 20 gram blob of wax falls on the disc and sticks to teh disc at a distance of 5 cm form its axis. Moment of inertia of the disc about its axit passing through its centre of mass is 2xx10^(-4) kg m^(2) . Calculate the new frequency of rotation of the disc.

A uniform disc is rotating freely about a vertical axis passing through its centre and makes 100 rpm. A small piece of gum of mass 8 g falls vertically on the disc and sticks to it at a distance of 5 cm from its axis. If the number of rotations per minute reduces to 80 rpm find the moment of inertia of the disc.

A horizontal disc rotating about a vertical axis passing through its centre makes 180 rpm. A small piece of wax of mass 10 g falls vertically on the disc and adheres to it at a distance of 8 cm from its axis. If the frequency is thus reduced to 150 rpm, calculate the moment of inertia of the disc.

A horizontal disc is rotating about a vertical axis passing through its centre. If an insect moves from centre to rim then the angular momentum of the system
