Answer

The torque on the particle about the origin is $(-50~\hat{k})~N~m$

Work Step by Step

We can find the torque on the particle about the origin as: $\tau = r\times F$ $\tau = (5\hat{i}+5\hat{j})~m\times (-10~\hat{j})~N$ $\tau = (-50~\hat{k}+0)~N~m$ $\tau = (-50~\hat{k})~N~m$ The torque on the particle about the origin is $(-50~\hat{k})~N~m$.
