Two forces of magnitudes 3N and 4 N act together on an object making an angle `60^(@)` with each other. Find the resultant force acting on the object.

Explanation

To find the resultant force acting on an object when two forces of magnitudes 3 N and 4 N act at an angle of 60 degrees to each other, we can use the law of cosines. Here’s the step-by-step solution:

### Step 1: Identify the Forces and the Angle
Let:
- \( A = 3 \, \text{N} \) (magnitude of the first force)
- \( B = 4 \, \text{N} \) (magnitude of the second force)
- \( \theta = 60^\circ \) (angle between the two forces)
