In the product \overrightarrow{F}=q(\overrightarrow{v}\times\overrightarrow{B}) =q \overrightarrow{v}\times(B \stackrel{\^}{i}+B \stackrel{\^}{j}+B_{0} \stackrel{\^}{k}) For q=1 and \overrightarrow{v}=2 \stackrel{\^}{i}+4 \stackrel{\^}{j}+6 \stackrel{\^}{k} and \overrightarrow{F}=4 \stackrel{\^}{i}-20 \stackrel{\^}{j}+12 \stackrel{\^}{k} What will be the complete expression for \stackrel{\^}{B} ? [NEET 2021]

Correct Answer is : −6^i−6^j−8^k

-8 \stackrel{\^}{i}-8 \stackrel{\^}{j}-6 \stackrel{\^}{k}

-6 \stackrel{\^}{i}-6 {j^{\^}}-8 {k^{\^}}

8 \stackrel{\^}{i}+8 \stackrel{\^}{j}-6 \stackrel{\^}{k}

6 \stackrel{\^}{i}+6 {j^{\^}}-8 {k^{\^}}
