A disc is rotating in the anticlockwise direction in the xy plane with decreasing angular velocity: What is direction of the angular acceleration ?

In example number 12.16 suppose the disc starts rotating anticlockwise with the same angular velocity omega=(v)/(R) , then what will be the angular momentum of the disc about bottommost in this new situation?

A frame of reference that is accelerated with respect to an inertial frame of reference is called a non-inertial frame of reference. A coordinate system fixed on a circular disc rotating about a fixed axis with a constant angular velocity omega is an example of non=inertial frame of reference. The relationship between the force vecF_(rot) experienced by a particle of mass m moving on the rotating disc and the force vecF_(in) experienced by the particle in an inertial frame of reference is vecF_(rot)=vecF_(i n)+2m(vecv_(rot)xxvec omega)+m(vec omegaxx vec r)xxvec omega . where vecv_(rot) is the velocity of the particle in the rotating frame of reference and vecr is the position vector of the particle with respect to the centre of the disc. Now consider a smooth slot along a diameter fo a disc of radius R rotating counter-clockwise with a constant angular speed omega about its vertical axis through its center. We assign a coordinate system with the origin at the center of the disc, the x-axis along the slot, the y-axis perpendicular to the slot and the z-axis along the rotation axis (vecomega=omegahatk) . A small block of mass m is gently placed in the slot at vecr(R//2)hati at t=0 and is constrained to move only along the slot. The net reaction of the disc on the block is

Two discs A and B are mounted coaxially ona vertical axle. The discs have moments of inertia l and 2l respectively about the common axis. Disc A is imparted an initial angular velocity 2 omega using the centre potential energy of a spring compressed by a distance x_(1) . Disc B is imparted angular velocity omega by a spring having the same spring constant and compressed by a distance x_(2) . Both the disc rotate in the clockwise direction. The loss of kinetic energy the above process is -

A negatively charged disc is rotated clock-wise. What is the direction of the magnetic field at any point in the plane of the disc?

An ideal inextensible string is wrapped over the disc of mass m and radius R. The other end of the string is connected to mass m. the string is passing over an ideal pulley A as shown in the figure. At any time t, mass m and disc are moving downward with acceleration of magnitude a_(1) " and " a_(2) respectively. The disc is rotating clockwise with angular acceleration of magnitude alpha . There is no slipping betweeb string and disc. choose the incorrect option

The magnetic field B shown in is directed into the plane of the paper. ACDA is a semicircular conducting loop of radius r with the centre at O. The loop is now made ot rotate clockwise with a constant angular velocity omega about on axis passing through O and perpendicular to the plane of the paper. The resistance of the loop is R. Obtain an expression for the magnitude of the induced current in the loop. Plot a graph between the induced current i and omegat , for two periods of rotation.

The figure shows a system consisting of (i) a ring the outer radius 3R rolling clockwise without slipping on a horizontal surface with angular speed omega and (ii) an inner disc of radius 2R rotating anti clockwise with angular speed omega//2. The ring and disc are separted. The point P on the inner disc is at a distance R from the origin, where OP makes an angle of 30^@ with the horizontal. Then with respect to the horizontal surface,

A metallic rod of length l is hinged at the point M and is rotating about an axis perpendicular to the plane of paper with a constant angular velocity omega .
