In the product$\overrightarrow F = q\left( {\overrightarrow v \times \overrightarrow B } \right)$$ = q\overrightarrow v \times \left( {B\widehat i + B\widehat j + {B_0}\widehat k} \right)$For q = 1 and $\overrightarrow v = 2\widehat i + 4\widehat j + 6\widehat k$ and $\overrightarrow F = 4\widehat i - 20\widehat j + 12\widehat k$What will be the complete expression for $\overrightarrow B $ ?

Question

In the product

$\overrightarrow F = q\left( {\overrightarrow v \times \overrightarrow B } \right)$

$ = q\overrightarrow v \times \left( {B\widehat i + B\widehat j + {B_0}\widehat k} \right)$

For q = 1 and $\overrightarrow v = 2\widehat i + 4\widehat j + 6\widehat k$ and $\overrightarrow F = 4\widehat i - 20\widehat j + 12\widehat k$

What will be the complete expression for $\overrightarrow B $ ?

$6\widehat i + 6\widehat j - 8\widehat k$

$ - 8\widehat i - 8\widehat j - 6\widehat k$

$ - 6\widehat i - 6\widehat j - 8\widehat k$

$8\widehat i + 8\widehat j - 6\widehat k$
