The region between y = 0 and y = d contains a magnetic field B^{\to} = Bz^{\^} . A particle of mass m and charge q enters the region with a velocity v^{\to} = vi^{\^}. If d = \frac{mv}{2qB} , the acceleration of thecharged particle at the point of its emergenceat the other side is :- [11 Jan 2019 Shift 2]

Correct Answer is : None of the above

{qvB}/m ({i^{\^}+j^{\^}}/\sqrt2)

{qvB}/m (1/2i^{\^}+\sqrt3/\sqrt2 j^{\^})

{qvB}/m ({-j^{\^}+i^{\^}}/\sqrt2)

{qvB}/m (\sqrt3/2i^{\^}+1/\sqrt2 j^{\^})
