Electric Repulsion VideoIn the video below, 1. Two balloons are held apart by two students holding thread aached to the balloons.2. Each balloon is given an electrical charge using an electrophorus. 3. The balloons are gently lowered towards each other unl the strings are slack and the balloons at rest, with all forces balanced4. You can use the protractor tool to measure the angle of deflecon, which shows us the force acng on each balloon.5. You can select the number of mes each balloon is charged (either one or two).The force on the balloons causes them to deflect -- to move apart and sit with their supporng strings at an angle. The amount of the deflecon depends on the amount of force on the balloons.Video instance not printed. Part 1: Deflecon and ForcePlay the video and watch as the balloons are charged and as they are allowed to move towards each other. Answer the following quesons.How can you tell that the balloons have the same kind of charge?

Objects with the same kind of charge aract.Because they have the opposite kind of charge they aract. Objects with the opposite kind of charge aract.Both balloons were charged by coming in contact with the electrophorus, so they were charged with the same kind of charge.Because they have the same kind of charge they repel. Objects with the same kind of charge repel each other.Use the protractor to measure the deflecon angle for each balloon. Which choice best describes the deflecon of the two balloons?The balloon on the right is deflected much more than the balloon on the le.The balloon on the le is deflected much more than the balloon on the right.The balloons are deflected about the same amount as each other.The angle of deflecon shows the amount of electric force on each balloon. A greater force causes the balloon to deflect to a greater angle. Since the two balloons are deflected to the same angle, we know that the force on each balloon must be the same. Why do you think the balloons have the same amount of force exerted on them?Electric forces are symmetrical, the electric repulsion of the balloons is equal because electric forces between two objects are always symmetrical.The electric forces are equal in this case because both balloons had the same amount of electric charge.Based on your answer above, what do you think would happen if one of the balloons had more electric charge than the other? How would this affect the electric force on each balloon? How would the angle of deflecon on each balloon change? Write your predicon of what would happen if one balloon has more charge in the space below.I think the angles of deflecon for both balloons will be equal to eachother even if one balloon had more charge.Response saved successfully. ×7/13/2020 Student Response | Pivot Interactiveshttps://app.pivotinteractives.com/assignments/5ec5dcd3ef99520024c20486/responses 3/5Secon is Locked1.2.3.1.Score: 0 / 2Score: 0 / 5Score: 0 / 5Score: 0 / 5 Part 2: Test your PrediconIn this secon, we'll explore what happens if the amount of charge is different on the two balloons.Use the video selecon tool to change the charge so the right balloon has more charge than the le balloon. Play the video and use the protractor to measure the deflecon. In the space below, describe what happened. They both have the same angles of deflecon, 21 degrees.Now use the video selecon tool to switch the charge so the le balloon has more charge than the right balloon. Describe the deflecon in this situaon. They both have the same angles of deflecon, 21 degrees.Based on these results, what would you predict would happen if even more charge was placed on only one of the balloons?The angles would remain equal to eachother. Part 3: Summarizing These ResultsLet's agree on a summary of what we observed.Which of these statements matches what we saw?Response saved successfully. ×7/13/2020 Student Response | Pivot Interactiveshttps://app.pivotinteractives.com/assignments/5ec5dcd3ef99520024c20486/responses 4/52.3.Select all that apply:Score: 5 / 5 3 / 10 submissions remainingScore: 0 / 5The amount of electric force depends on the amount of charge. Adding more charge to either balloon caused a greater repulsive force.If the one balloon has more electric charge, that causes a greater electric force on only on the other balloon.If the one balloon has more electric charge, that causes a greater electric force on only on itself, causing that balloon to move farther away than the other balloon.If the one balloon has more electric charge, that causes a greater electric force on both balloons, causing them to deflect equally.Submit AnswerStudent Jorge says:The balloons always deflect away from the center the same amount. That shows that the force on both balloons is the same. This means that the le balloon exerts the same amount of force on the right balloon as the right balloon exerts on the le. The forces on each balloon are always the same. Bryce says:When the amount of charge added to the balloons increased, the amount of deflecon of the balloons increased. This shows that the amount of force depends on the the amount of charge added. So if the right balloon has more charge than the le balloon, it must apply a greater force than the le balloon. Which parts of each students' statements matches your observaon from the videos?As the charge on anything increases, so does the electric force.The balloons always deflect away from the center the same amount.You may have heard Newton's third law stated like this:For every acon there is an equal and opposite reacon.Another way
