(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Force F⃗ =−11j^N is exerted on a particle at r⃗ = (8i^+5j^)m.

What is the torque on the particle about the origin? Express your answer using two significant figures. Enter coordinates numerically separated by commas.

2. Relevant equations

3. The attempt at a solution

F: 0i, -11j, 0k

r: 8i, 5j, 0k

F X r = (0-0)i - (0-0)k + (0 - -88)j

= 0, 0, 88

this is wrong because it should be -88, but I dont see why? It was my understanding that I should plug values into formula i - j + k. Thanks for any help.
