A wire is bent in a parabolic shape followed by equation `x=4y^(2)` consider origin as vertex of parabola a wire parallel toy axis moves with constant speed 4m/s along x-axis in the plane of bent wire. Then the acceleration of touching point of straight wire and parabolic wire is (when straight wire has x coordinates `=4m`)

If a current I is flowing in a straight wire parallel to X - axis and magnetic field is in Y - axis then the wire experiences

A thin uniform wire of mass m and length l is bent into to shape of a semicircle. The moment of inertia of that wire about an axis passing through its free ends is

A rod of length l is kept parallel to a long wire carrying constant current i . It is moving away from the wire with a velocity v . Find the emf induced in the wire when its distance from the long wire is x .

A piece of wire is bent in the shape of a parabola y=kx^(2) (y-axis vertical) with a bead of mass m on it. The bead can slide on the wire without friction. It stays at the lowest point of the parabola when the wire is at rest. The wire is now accelerated parallel to the x-axis with a constant acceleration a. The distance of the new equilibrium position of the bead, where the bead can stay at rest with respect to the wire, from the y-axis is:
