Given:
- Magnitude of force f1 = 5N
- Magnitude of force f2 = 5N
- Angle between the forces = 60°

To find:
- Resultant force acting on the body

Step 1: Resolving the forces
The two forces f1 and f2 can be resolved into their components along the x-axis and y-axis. Let's assume f1 is along the positive x-axis and f2 is inclined at an angle of 60° with respect to f1.

The x-component of f1 (f1x) can be calculated using the formula:
f1x = f1 * cosθ
where θ is the angle between f1 and the x-axis.
In this case, θ = 0°, so cosθ = 1.
Therefore, f1x = f1 * cos0° = f1 = 5N.

The y-component of f1 (f1y) can be calculated using the formula:
f1y = f1 * sinθ
where θ is the angle between f1 and the x-axis.
In this case, θ = 0°, so sinθ = 0.
Therefore, f1y = f1 * sin0° = 0N.

The x-component of f2 (f2x) can be calculated using the formula:
f2x = f2 * cosθ
where θ is the angle between f2 and the x-axis.
In this case, θ = 60°.
Therefore, f2x = f2 * cos60° = f2 * 0.5 = 5N * 0.5 = 2.5N.

The y-component of f2 (f2y) can be calculated using the formula:
f2y = f2 * sinθ
where θ is the angle between f2 and the x-axis.
In this case, θ = 60°.
Therefore, f2y = f2 * sin60° = f2 * 0.866 = 5N * 0.866 = 4.33N.

Step 2: Finding the resultant force
The resultant force can be calculated by adding the x-components and y-components of the forces.

The x-component of the resultant force (Rx) is the sum of f1x and f2x:
Rx = f1x + f2x = 5N + 2.5N = 7.5N.

The y-component of the resultant force (Ry) is the sum of f1y and f2y:
Ry = f1y + f2y = 0N + 4.33N = 4.33N.

The magnitude of the resultant force (R) can be calculated using the Pythagorean theorem:
R = √(Rx² + Ry²)
R = √((7.5N)² + (4.33N)²)
R = √(56.25N² + 18.76N²)
R = √(75.01N²)
R = 8.66N (approximately)

Step 3: Finding the direction of the resultant force
The direction of the resultant force can be found using the tangent

Use the method of vector form |F|=|F1 vector| + | F2 vector| solve by this method u get the answer as 8.66N ..!!👍👍
