What is the torque of the force vecF=3hati-2hatj+4hatk acting at a poi

1.	What is the torque of the force vecF=3hati-2hatj+4hatk acting at a point vecr=2hati+3hatj+5hatk about the origin?
Answer» Solution :`vec tau= vec r XX vecF = \|(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 `
