Constant forces `P_(1)=hati-hatj+hatk, P_(2)= -hati+2hatj-hatik and P_(3)=hatj-hatk` act on a particle at a point A . Determine the work done when particle is displaced from position `A(4hati-3hatj-2hatk) " to" B (6hati+hatj-3hatk)`

Explanation

To solve the problem step by step, we will follow these steps:

### Step 1: Write down the given forces and positions
The forces acting on the particle are:
- \( P_1 = \hat{i} - \hat{j} + \hat{k} \)
- \( P_2 = -\hat{i} + 2\hat{j} - \hat{k} \)
- \( P_3 = \hat{j} - \hat{k} \)
