Find the torque of a force `F=(2hat(i) +hat(j)-3hat(k))N` about a point O. The position vector of point of application of force about O is `r = (2 hat(i) + 3 hat(j) - hat(k))m`.

Explanation

To find the torque of the force \( \mathbf{F} = (2\hat{i} + \hat{j} - 3\hat{k}) \, \text{N} \) about point \( O \), we need to use the formula for torque, which is given by the cross product of the position vector \( \mathbf{r} \) and the force vector \( \mathbf{F} \):

\[ \mathbf{\tau} = \mathbf{r} \times \mathbf{F} \]

### Step 1: Identify the vectors
The position vector \( \mathbf{r} \) is given as:
