The region between y =0 and y=d constains a magnetic field vecB = Bvecz . A particle of mass m and charge q enters of the region with a velocity vecv = v veci . If d =(mv)/(2qB) the acceleration of the charged particle at the point of its emergence at the other side is :

A particle of mass m and charge q is projected into a region having a perpendicular magnetic field B. Find the angle of deviation of the particle as it comes out of the magnetic field if ihe width d of the region is (2mv)/(qB)

A charge particle of mass m and charge q is projected with velocity v along y-axis at t=0. Find the velocity vector and position vector of the particle vec v (t) and vec r (t) in relation with time.

A charge particle of mass m and charge q is projected with velocity v along y-axis at t=0. Find the velocity vector and position vector of the particle vec v (t) and vec r (t) in relation with time.

The region between x=0 and x=L is filled with uniform steady magnetic field B_0hatk . A particle of mass m, positive charge q and velocity v_0hati travels along x-axis and enters the region of the magnetic field. Neglect the gravity throughout the question. Find the value of L if the particle emerges from the region of magnetic field with its final velocilty at an angel 30^@ to its initial velocity.
