Two forces each numerically equal to 5N are acting as shown in the figure, then find resultant of these two vectors.

Explanation

To find the resultant of two forces each numerically equal to 5N acting at an angle of 120 degrees to each other, we can use the vector addition formula for two vectors.

Given:
- Magnitude of each force, \( F_1 = F_2 = 5 \, \text{N} \)
- Angle between the forces, \( \theta = 120^\circ \)

We use the formula for the resultant of two vectors:
\[ R = \sqrt{F_1^2 + F_2^2 + 2F_1F_2 \cos \theta} \]
