The friction force affecting the body in the opposite figure is


5 N

10 N

20 N

40 N

To solve this problem, we need to determine the frictional force acting on the object based on the given information. Let's break it down step-by-step:

### Information given:
1. Mass of the block (\(m\)) = 4 kg  
2. Applied force (\(F\)) = 50 N  
3. Acceleration (\(a\)) = 10 m/s²  
4. Frictional force opposes the motion.

### Step 1: Calculate the net force (\(F_{\text{net}}\)) acting on the object.
Using Newton's second law of motion:  
\[
F_{\text{net}} = m \cdot a
\]
Substituting the given values:
\[
F_{\text{net}} = 4 \cdot 10 = 40 \, \text{N}
\]

### Step 2: Relating the forces.
The net force is the result of the applied force minus the frictional force:
\[
F_{\text{net}} = F - F_{\text{friction}}
\]
Rearranging to find the frictional force:
\[
F_{\text{friction}} = F - F_{\text{net}}
\]

Substitute the values:
\[
F_{\text{friction}} = 50 - 40 = 10 \, \text{N}
\]

### Final Answer:
The frictional force is **10 N**.
