A charge q is moving with a velocity \overrightarrow{V}_{1}=\hat{i} m \/ s at a point in a magnetic field and experience a force \overrightarrow{F}_{1}=q[-1 \hat{j}+1 \hat{k}] N. If the charge is moving with a velocity \overrightarrow{V}_{2}=1 \hat{j} m \/ s at the same point,it experience a force \overrightarrow{F}_{2}=q[\hat{1i}-\hat{1k}] N. If the magnetic induction \overrightarrow{B} at that point is {B}^{\to }= \stackrel{⋀}{a{i}} + {b} \stackrel{⋀}{j}+ {ck^{⋀}} calculate a+b+c.
