Gravitational field at the centre of semicircle formed by a thin wire AB of mass m and length l is
A thin rod of length L is bent to form a semicircle. The mass of the rod is M. What will be the gravitational potential at the centre of the semicircle?
A wire as shown in the figure carries a current of 2A.The semicircle has radius of 4cm, the magnetic field at the center C will be
A thin wire of length l and mass m is bent in the form of a semicircle as shown in the figure. Its moment of inertia about an axis joining its free ends will be
