A pair of bullocks exerts a force of `140 N` on a plough. The field being ploughed is `15 m` long. How much work is done in ploughing the length of the field?

Explanation

To solve the problem of how much work is done in ploughing the length of the field, we can follow these steps:

### Step 1: Identify the given values
- Force exerted by the bullocks (F) = 140 N
- Distance (displacement) of the field being ploughed (d) = 15 m

### Step 2: Use the formula for work done
The formula for work done (W) is given by:
