1.	You are given a cube, a ring, a cylinder and a sphere, all having equal masses and cross sections with equal heights and maximum widths. Which one has the largest and which one has smallest moment of inertia about an axis perpendicular to the cross section and passing through the centre of mass.
Answer» Solution :We KNOW that `I sum(mr^2)`. Here ring has the largest moment of inertia because it.s mass is situated farthest from the AXIS of rotation while the sphere has least moment of inertia as it.s mass is NEAREST to the axis of rotation.

A wire is bent to form a semicircle of the radius a. The wire rotates about its one end with angular velocity omega . Axis of rotation is perpendicular to the plane of the semicircle . In the space , a uniform magnetic field of induction B exists along the aixs of rotation as shown in the figure . Then -
A massless non conducting rod AB of length 2l is placed in uniform time varying magnetic field confined in a cylindrical region of radius (R gt l) as shown in the figure. The center of the rod coincides with the centre of the cylin- drical region. The rod can freely rotate in the plane of the Figure about an axis coinciding with the axis of the cylinder. Two particles, each of mass m and charge q are attached to the ends A and B of the rod. The time varying magnetic field in this cylindrical region is given by B = B_(0) [1-(t)/(2)] where B_(0) is a constant. The field is switched on at time t = 0. Consider B_(0) = 100T, l = 4 cm(q)/(m) = (4pi)/(100) C//kg. Calculate the time in which the rod will reach position CD shown in the figure for th first time. Will end A be at C or D at this instant ?
