A particle of mass m, positive charge q and velocity v0i travels along x-axis and enters the region of the magnetic field. Neglect the gravity throughout the question. a. Find the value of l if the particle emerges from the region of magnetic field with its final velocity at an angel 30 to its initial velocity.

A uniform constant magnetic field B is directed at an angle of 45 to the x-axis in the xy- plane . PQRS is a rigid An electron gun G emits electrons of energy 2keV travelling in the positive x-direction. The electrons are required to hit the spot S where GS = 0.1m and the line GS makes an angle of 60 with the x-axis as shown in figure. A uniform magnetic field B parallel to GS exists in the region outside the electron gun. square wire frame carrying a steady current I0 the frame is at rest in the position as shown in figure The region between x=0 and x=L is filled with uniform steady magnetic field B0k. A particle of mass m with its centre at the origin O. At time t=0
