A charge particle having charge q expericenec a `F_(1)q=(-hatj+hatk)N ` in a magnetic field B when is has velocity `v_(1)=(1.0)hati(m)/(s)`. The force becomes `F=q(hati-hatk)` when the velocity is charged to `v_2 = 1.0hatj(m)/(s)` magnetic induction vector at that point is

A

`(hati+hatj+ hatk)T`

B

`(hati-hatj- hatk)T`

C

`(-hati-hatj+ hatk)T`

D

`(hati+hatj- hatk)T`
