There are two concentric circular loops. One loop of radius r is made up of only one turn. The other loop has a radius 2r and has two turns of wire. They are arranged such that they have a common centre and their planes are perpendicular to each other. When the same current i is passed through both the coils, the magnetic field at the common centre is

The moment of intertia of a disc about an axis passing through its centre and normal to its plane is I. The disc is now folded along a diameter such that the two halves are mutually perpendicular. Its moment of inertia about this diameter will now be

Two coins of diameter 2 cm and 4 cm respectively are kept one over the other as shown in the figure the area of the shaded ring shaped region is ___ square cm.

Two circular rings each of mass M and radius R are attached to each other at their rims and their planes perpendicular to each other as shown in figure. The moment of inertia of the system about a diameter of one of the rings and passing through the point of contanct is

Two fixed insulating rings A and B carry ahanges with uniform linear aharge density +lambda and -lambda , respectively, as shown in the adjacent figure. The planes of the rings are parallel to each other and their axes are coinciding. A particle of change "q" and mass "m" is released with zero velocity from centre P of the positively charged ring. The kinetic energy of the particle when it reaches centre Q of the negatively charge ring will be

At the centre of a fixed large circular coil of radius R a much smaller circular coil of radius r is placed .The two coils are concentric and are in the same plane .The larger coil carries a current I The smaller coil is set to rotate with a constant angular velocity omega about an axis along their common diameter .Calculate the emf induced in the smaller coil after a time t of its start of ratation

A bead of mass m can slide without friction along a vertical ring of radius R. One end of a spring of force constant k=(3mg)/(R ) is connected to the bead and the other end is fixed at the centre of the ring. Initially, the bead is at the point A and due to a small push it starts sliding down the ring. If the bead momentarily loses contact with the ring at the instant when the spring makes an angle 60^(@) with the vertical, then the natural length of the spring is
