A force `F=(2hati+3hatj+4hatk)N` is acting at point `P(2m,-3m,6m)` find torque of this force about a point `O` whose position vector is
`(2hati-5hatj+3hatk)` m.

Explanation

To find the torque of a force \( \mathbf{F} = (2\hat{i} + 3\hat{j} + 4\hat{k}) \, \text{N} \) acting at point \( P(2 \, \text{m}, -3 \, \text{m}, 6 \, \text{m}) \) about point \( O \) whose position vector is \( \mathbf{R_O} = (2\hat{i} - 5\hat{j} + 3\hat{k}) \, \text{m} \), we will follow these steps:

### Step 1: Determine the position vectors
First, we need to define the position vectors for points \( P \) and \( O \):
- Position vector of point \( P \):
\[ \mathbf{R_P} = 2\hat{i} - 3\hat{j} + 6\hat{k} \, \text{m} \]
