A force `(hati-2hatj+3hatk)` acts on a particle of positive vector `(3hati+2hatj+hatk)`. Calculat the torque acting on the particle.

Text Solution

Verified by Experts

`vectau=vecrxxvecF`.
using Determinant method
`vectau=|{:(hati,hatj,hatk),(3,2,1),(1,-2,3):}|`
`impliesvectau=8(hati-hatj-hatk)`Nm.
