(adsbygoogle = window.adsbygoogle || []).push({}); [SOLVED] Vector products and torque

1. The problem statement, all variables and given/known data

A particle is located at the vector position r = (i + 3j) m, and the force acting on it is F = (1i + 7j) N.

(a) What is the torque about the origin?

(b) What is the torque about the point having coordinates (0, 4) m?

3. The attempt at a solution

I got the answer for the first part, but I am confused about part b. At first I thought I was supposed to just switch (i +3j) with (0,4) but that is not right. So then I thought that maybe I was supposed to do this:

(1,3) - (0,4) = new vector, and the coordinates for the new vector to find the torque which would be equal to 8 nm. Is that how I am supposed to do it?
