Magnetic induction field is existing along `+Z` axis in a region `0lexlea(a` is positive `)`. A point charge `q` is projected with a velocity `'v'` at origin along positive `x-` axis , choose the correct alternative regarding its deviation.

A

maximum deviation is `pi` rad independent of value of `a`

B

maximum deviation is `pi//2` rad independent of value of `a`

C

maximum deviation is `pi//2` rad if `a` is greater then its radius of curvature

D

Maximum deviation is `pi//2` rad only if a equal to its radius of curvature.
