Consider the plane of the paper to be vertical plane with direction of ′g′ as shown in the figure. A rod (MM′) of mass ′M′ and carrying a current I. The rod is suspended vertically through two insulated spring of spring constant K at two ends. A uniform magnetic field is applied perpendicular to the plane of the paper such that the potential energy stored in the spring, in equilibrium position is zero. If the rod is slightly displaced in the vertically direction from the position of equilibrium, then the time period of oscillation is

In a certain region of space, there exists a uniform and constant electric field of magnitude E along the positive y-axis of a coordinate system. A charged particle of mass m and charge -q (qgt0) is projected form the origin with speed 2v at an angle of 60^@ with the positive x-axis in x-y plane. When the x-coordinate of particle becomes sqrt3mv^2//qE a uniform and constant magnetic. field of strength B is also switched on along positive y-axis. z-coordinate of the particle as a function of time after the magnetic field is switched on is

A insulated square frame ABCD of side a is able to rotate about one of its side taken as positive z-axis. A magnetic field B is present in the region given by vecB=B_(0)hatj. A small block of mass m and charge q movable along side CB is initially near C, when frame lies in x-z plane. Now, frame is rotated by constant angular velocity omega about z-axis. Whole system lies in gravity free space. If after time t block reaches point B, find B_(0) in terms of t.
