If a person moves a trolley for a distance of 10 m with a force of 50 , then the work done is:

Options

A. 0.2 J
B. 5 J
C. 20 J
D. 500 J

Answer

To solve the problem of calculating the work done when a person moves a trolley, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the given values**:
- Force (F) = 50 Newtons
- Distance (d) = 10 meters

2. **Understand the formula for work done**:
- The formula to calculate work done (W) is:
\[ W = F \times d \]
where \( W \) is the work done, \( F \) is the force applied, and \( d \) is the distance moved in the direction of the force.

3. **Substitute the values into the formula**:
- Plugging in the values we have:
\[ W = 50 \, \text{N} \times 10 \, \text{m} \]

4. **Perform the multiplication**:
- Calculate the product:
\[ W = 500 \, \text{N m} \]

5. **Convert the units**:
- The unit of work done is Joules (J), and since \( 1 \, \text{N m} = 1 \, \text{J} \):
\[ W = 500 \, \text{J} \]

6. **Conclusion**:
- Therefore, the work done is 500 Joules.

### Final Answer:
The work done is **500 Joules**.
