Transcribed Image Text:**Educational Content: Understanding Equilibrium Forces**
**Problem Statement:**
In this problem, you place a 100 gram mass on a string and hang it from the table at an angle of 265 degrees. Next, you hang a 200 gram mass from the table at an angle of 195 degrees.
Next, at what angle would you need to place this equilibrium force to achieve a net force of 0? Give your answer to 2 significant figures. We understand the answer means "degrees"; however, do not include "degrees" in your answer. Only type in the number.
**Diagram Explanation:**
The diagram is a circular protractor, marked with degrees from 0 to 360, representing a 360-degree coordinate system. Two vectors are depicted:
1. **Vector \( \vec{F_1} \):**
- Direction: Downward from the center.
- Angle: Marked as 195 degrees on the protractor.
- Representing the force exerted by the 200 gram mass.
2. **Vector \( \vec{F_2} \):**
- Direction: Angled upwards and to the left.
- Angle: Marked as 265 degrees on the protractor.
- Representing the force exerted by the 100 gram mass.
For equilibrium, these forces need to be balanced by a third force at a specific angle, achieving a net force of zero.

Transcribed Image Text:**Experiment Overview**
You are performing an experiment using the force table shown in the image.
**Experimental Details**
- **Tension Force 1 (\(F_{T1}\))**:
- Mass: 0.4 kg
- Angle: 165° relative to the "x" axis or 0° marker.
- **Tension Force 2 (\(F_{T2}\))**:
- Mass: 1 kg
- Angle: 240°.
**Objective**
Determine the magnitude of tension force 3 (\(F_{T3}\)) required for static equilibrium. Note that \(F_{T3}\) is not shown in the image.
**Instructions**
- Your answer should be in units of Newtons, but do not include "N" in your answer.
- Only numerical answers are accepted.
**Image Description**
The image contains a circular protractor with markings every 10 degrees from 0° to 360°. Two red arrows represent tension forces:
- \(F_{T1}\) is placed at 165°.
- \(F_{T2}\) is placed at 240°.
The forces originate from the center of the protractor, indicating the angles at which they act.
