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 \(\overrightarrow B\) ?
