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.
