In the figure there are two identical conducting rods each of length a rotating with angular speed omega is the direction shown.One end of each rod touches a conducting ring.Magnetic field B exists perpendicular to the plane of the rings.The rods the conducting rings and the lead wires and resistanceless.Find the magnitude and direction of current in the resistance R .

A cylindrical copper rod has length L and resistance R. If it is melted and formed into another rod of length 2L, the resistance will be

A metal rod of length 'L' and mass 'm' is piovted at one end. A thin disk of mass 'M' and radius 'R' (lt L) . Is attached at its centre to the free end of the rod. Consider two ways the disc is attached: (case A ). The disc is not free to rotate about its centre and (case B ) the disc is free to rotate about its center. The rod-disc sustem perform SHM in vertical plane after being released from the same displaced potion. Which of the following statement(s) is (are) true?

A rod of length L and resistance r rotates about one end as shown in . Its other end touches a conducting ring of negligible resistence. A resistence R is connected between the center and periphery. Draw the electrical equivalence and find the current in resistance R . There is a uniform magnetic field B directed as shown in .

A rod having length L, density D and area of Cross-section A is rotating about the centre with velocity @ and perpendicular to its length. Its rotational kinetic energy is

A uniform rod of mass m and length L lies radialy on a disc rotating with angular speed omega in a horizontal plane about vertical axis passing thorugh centre of disc. The rod does not slip on the disc and the centre of the rod is at a distance 2L from the centre of the disc. them the kinetic energy of the rod is

One end of a metal rod of length L and mass M is pivoted to a fixed support and to its free end, a thin disc of mass m and radius r (L) is attached at its centre. In one case, the disc is attached to the rod in such a way that it is not free to rotate about its centre and in another case, teh disc is free to rotate about its centre. When the rod-disc system is displaced slightly from its equilibrium position and released. it peforms S.H.M. in vertical plane. Compare the restoring torque acting on the system and angular frequency in both the cases.

A uniform rod of length l is from rest such that it rotates about a smooth pivot. The angular speed of the rod when it becomes vertical is. .
