A particle of specific charge `q//m = (pi) C//kg` is projected from the origin towards positive x-axis with a velocity of `10 m//s` in a uniform magnetic field `vec(B) = -2 hat K` Tesla. The velocity `vec V` of the particle after time `t =1//6` s will be

`(5hati+5sqrt3hatj)m//s`

`10hatJm//s`

`(5sqrt3hati-5hatj)m//s`

`-10hatjm//s`
