\overrightarrow F = \widehat i + 2\widehat j - 3\widehat k

and

\overrightarrow r = 2\widehat i - \widehat j + \widehat k

. Find

\overrightarrow r \times \overrightarrow F

View answer and explanation

Correct option: B

\widehat i + 7\widehat j + 5\widehat k

Option B (

\widehat i + 7\widehat j + 5\widehat k

) is correct because it is the result of the cross product of the two given vectors.
