What will be the net force if two forces of 20N and 10 N are acting on a body in opposite directions?

Options

A. 10 N
B. 25 N
C. 30 N
D. 35 N

Answer

To find the net force acting on a body when two forces are applied in opposite directions, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Forces**: We have two forces acting on the body:
- Force 1 (F1) = 20 N (acting in one direction)
- Force 2 (F2) = 10 N (acting in the opposite direction)

2. **Determine the Direction**: Since the forces are acting in opposite directions, we can assign a direction to each force. For example, we can consider the direction of F1 (20 N) as positive and the direction of F2 (10 N) as negative.

3. **Calculate the Net Force**: The net force (F_net) can be calculated by subtracting the smaller force from the larger force:
\[ F_{net} = F1 - F2 \]
Substituting the values:
\[ F_{net} = 20 N - 10 N = 10 N \]

4. **Determine the Direction of the Net Force**: Since F1 (20 N) is greater than F2 (10 N), the net force will be in the direction of F1. Therefore, the net force is 10 N in the direction of the 20 N force.

### Final Answer:
The net force acting on the body is **10 N** in the direction of the 20 N force.
