What is the torque of the force `vecF=(2hati+3hatj+4hatk)N` acting at the point `vecr=(2hati+3hatj+4hatk)m` about the origin? (Note: Tortue, `vectau=vecrxxvecF`)

Text Solution

Verified by Experts

`"Torque" vectau=vecrxxvecF=|{:(hati,hatj,hatk),(2,3,4),(2,3,4):}|=hati(12-12)-hatj(8-8)+hatk|6-6|=0hati-0hati-0hatj+ohatk=vec0`
