Two forces of 12 N and 5 N are acting on a particle , with an angle of `60^(@)` between them , Calculate the resultant force .

Explanation

To solve the problem of finding the resultant force when two forces of 12 N and 5 N are acting on a particle at an angle of 60 degrees between them, we can use the parallelogram law of vector addition. Here’s a step-by-step solution:

### Step 1: Identify the Forces and the Angle
We have two forces:
- \( F_1 = 12 \, \text{N} \)
- \( F_2 = 5 \, \text{N} \)
- The angle between them is \( \theta = 60^\circ \).
