Given veca = hati-hatj+hatk and vecb = 2...

Given `veca = hati-hatj+hatk` and `vecb = 2hati-4hatj-3hatk`, find the magnitude of `veca-vecb`

Text Solution

Verified by Experts

`veca-vecb = (hat-hatj+hatk)+(2hati-4hatj-3hatk)= -hati+3hatj+4hatk`
`|veca-vecb| = |-hati+3hatj+42hatk|= sqrt((-1)^2+3^2+4^2) = sqrt(26)`
