Two constant forces `vec(F)_(1) = 6hat(i) +3hat(j)-hat(k) and vec (F)_(2) = 3hat(i) - 2hat(j) +hat(k)` are acting upon a body along the same direction . Calculate the work done by these forces if the body is displaced from the point (2,1,2) to (3,-4,-5) .

Explanation

To solve the problem, we will follow these steps:

### Step 1: Calculate the Net Force
We have two forces acting on the body:
\[ \vec{F}_1 = 6\hat{i} + 3\hat{j} - \hat{k} \]
\[
