If `vec(A)+2hati-hatj and vecB=4hati+3hatj` then, obtain the scalar magnitude and direction from x - axis of,
`vecB`

Text Solution

Verified by Experts

`vecA=2hati-hatj, vecB=4hati+3hatj`
For `vecB`:
Direction of `vecB=tan theta=(3)/(4), theta=tan^(-1)=((3)/(4))`
Magnitude of `vecB=sqrt((4)^(2)+(3)^(2))=sqrt(16+9)-sqrt(25)=5`
