What are the resultants of the vector product of two given vectors. Given by
`vecA=4hati-2hatj+hatk and vecB=5hati+3hatj-4hatk`

Text Solution

Verified by Experts

`vecA=4hati-2hatj+hatk`
`vecB=5hati+3hatj-4hatk`
Resultant vector `=vecA xx vecB=|(hati, hatj,hatk),(4,-2,1),(5,3,-4)|`
`=[(8-3)hati-(-16-15)hatj+(12+10)hatk]`
Resultant vector `=5hati+21hatj+22hatk`
