A charged particle having charge q experiences a force F⃗ =q(−j^+k^) N in a magnetic field B when it has a velocity v1=1i^ m/s. The force becomes F⃗ =q(i^−k^) N when the velocity is changed to v2=1j^ m/s. The magnetic induction vector at that point is :
A. (i^+j^+k^) T
B. (i^−j^−k^)T
C. (−i^−j^+k^) T
D. (i^+j^−k^)T
