Two vectors are given as `vecr=2hati+3hatj+5hatkandvecF=3hati-2hatj+4hatk`. Find the resultant vector `vectau=vecrxxvecF`.

Text Solution

Verified by Experts

`tau = vecr xx vec F = | (hati, hatj , hatk),(2,3,5),(3,-2,4)|`
` tau = (12 - (-10) ) hati (15 - 8) hatj + (-4 - 9) hatk`
`tau = 22 hati + 7 hatj - 13 hatk `
