### Definition of torque

A particle is located at $\vec{r}=\left(0.54m\right) \hat{i}+\left(-0.36m\right) \hat{j}+\left(0.85m\right) \hat{k}$. A constant force of magnitude 2.6N acts on the particle. find the components of the torque about the origin when the force acts in
a) the positive $\hat x$ direction.
b) the negative $\hat z$ direction.
