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

The correct Answer is:
Given: Vectors `vecA=4hati-2hatj+hatk`
`vecB=5hati+3hatj-4hatk`
Vector product `vecAxxvecB=|{:(hati,hatj,hatk),(4,-2,1),(5,3,-4):}|`
`=hati(8-3)-hatj(-16-5)+hatk(12+10)=5hati+21hatj+22hatk`
