**Finding the Net Force on an Object with Applied Forces**

**Problem Statement:**
Two forces are applied to an object as shown in the diagram. Using \( F_1 = 27 \, \text{N} \), \( \phi_1 = 55^\circ \), \( F_2 = 31\, \text{N} \), and \( \phi_2 = 17^\circ \), find the net force on the object.

**Diagram Explanation:**
The diagram depicts a coordinate system with two forces \( F_1 \) and \( F_2 \) acting on an object at the origin. \( F_1 \) is directed at an angle \( \phi_1 = 55^\circ \) counterclockwise from the positive x-axis, and \( F_2 \) is directed at an angle \( \phi_2 = 17^\circ \) counterclockwise from the negative x-axis.

**Questions:**

2. **Magnitude:**
   - A. 18.22 N
   - B. 12.01 N
   - C. 31.43 N
   - D. 19.26 N
   - E. 21.03 N
   - F. 30.75 N

3. **Direction (counter-clockwise from +x axis):**
   - A. 148.5°
   - B. 175.2°
   - C. 236.2°
   - D. 142.3°
   - E. 137.3°
   - F. 250.7°

**Review Strategy:**
To find the resultant force:
1. Use vector components to break down \( F_1 \) and \( F_2 \) into \( x \) and \( y \) components.
2. Sum the components in each direction to get the resultant vector.
3. Calculate the magnitude of the resultant vector using \( \sqrt{R_x^2 + R_y^2} \).
4. Determine the direction of the resultant vector using \( \tan^{-1}(R_y/R_x) \).

By following these steps, students can effectively find both the magnitude and direction of the net force.
