Question
What are the resultants of the vector product of two given vectors given by `vecA = 4hati - 2hatj + hatk` and `vecB = 5hati + 3hatj - 4hatk`?
Solution
Given,
Vectors `vecA = 4hati - 2hatj + hatk`
`vecB = 5hati + 3hatj - 4hatk`
Solution:
Vector product `vecA xx vecB = |[hati, hatj, hatk], [4, -2, 1], [5, 3, -4]|`
= `hati(8 - 3) - hatj(-16 - 5) + hatk(12 + 10) = 5hati + 21hatj + 22hatk`
