1.	A thin and uniform rod of mass M and length L is held vertical on floor with large friction. The rod is released from rest so that is falls by rotating about is contact-point with the floor without slipping. Which of the following statement(s) si/are correct. When the rod makes an angle 60^(@)with vertical? [g is the acceleration due to gravity]
Answer» TheNormal REACTION force from the floor onthe rod will be `(Mg)/(16)` The angular acceleration of the rod will be`(2g)/(L)` The angular speed of the rod will be`sqrt((3g)/(2L))` The radial acceleration of the rod's center ofmass will be `(3g)/(4)` Answer :A::C::D

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 ?
