As I rub the balloons in my hair, I am picking up positive charges from my hair, which are electrons. The static charge produced will remain active on the balloons, so when they are stuck to the wall by attraction, and then repel one another. Given that the fundamental laws of nature tells us that no charge can be created nor destroyed, I think of the balloons as holding two magnets with the same negative…
Introduction: This experiment was to investigate the concept of the electric field, and to determine the shape of equal potential lines surrounding charged objects.…
3. Reflect on your ideas from question #1 and your data from question #2. How do your observations support, dispute or add to your ideas about what affects how charged bodies interact?…
The sources of error could have been in measuring the angle o敬杮桴漠桴瑳楲杮桔瑳楲杮洠杩瑨栠癡敢湥愠氠瑩汴桳牯整r length of the string. The string might have been a little shorter or longer than measured. The angle could have varied based on the electrostatic they already had between them at the moment. The angle could have been slight smaller or larger than the measurement taken by the protractor.…

A charged object will attract an uncharged object until they touch, and then they will repel one another. When charged objects attract uncharged objects, such as when the negatively charged plastic comb or fur attracted the paper, the negatively charged comb/fur repelled some of the electrons in the paper. This results in a redistribution of charges in the paper so that one side is more negative than the other side. The net effect is that the paper is attracted to the comb/fur. This also applies to the balloon attracting an uncharged wall. When a charged object is placed near an uncharged object, its charges rearrange themselves. In other words, those charges attracted to the charged object move towards the charged object and those charges repelled move away. This effect is known as polarization.…
12. When you rub a balloon on your hair, your hair is attracted to the balloon because both the hair and the balloon have become electrically charged. True…

D. If a third type of charge existed, how would it affect the two oppositely charged strips in this activity?…
a positive ion (cation) and a negative ion (anion) are strongly attracted to one another. In this experiment, a…

Hypothesis: I fully believe that the charge of the pith ball will be positive. The formula I will use to prove this is Coulomb’s Law, (Fe=(k*q1*q2) / r²). ‘Fe’ is equal to the electrostatic force between the spheres, measured in Newton’s. It is also a vector quantity, and it’s in absolute value. Secondly, ‘k’ is equal to Coulomb’s law constant. The constant is equal to 8.99 * 10^9 N*m²/C². Thirdly, ‘q1’ is equal to the charge in Coulomb’s (C) of the first object. As well, ‘q2’ is equal to the charge of the second object in Coulomb’s (C). Finally, ‘r²’ is equal to the radius between the two centres of the objects measured in metres, squared. The manipulated variable in this lab is the radius at which we place the metal sphere away from the pith ball. The responding variable is the electrostatic force of the pith ball as a result of the radius from the metal sphere. The controlled variable is the charge of the metal sphere, which is -3.59e-7C.…
NEGATIVE CHARGE Think If a piece of gold is rubbed with a piece of wool, which object loses electrons Explain using the electrostatic series. The wool is at the top of the electrostatic series so will lose electrons and have a positive charge. The gold is lower on the electrostatic series so gold will gain electrons and have a negative charge. If a piece of gold is rubbed with a piece of wool, the wool loses electrons. The gold gains electrons. Wool is an electron giver and gold is an electron taker. Name one substance that will get a negative charge when rubbed on ebonite. Copper, rubber or gold Name one substance that will get a positive charge when rubbed on ebonite. acetate, glass, wool or human hair One piece of glass is rubbed with silk. A second piece of glass is rubbed with a rubber balloon. What will be the charge on both pieces of glass The glass will have a positive charge when rubbed with either silk or rubber. Which piece of glass will have a stronger charge and explain why. The glass rubbed with rubber will have a stronger positive charge because rubber and glass are further apart on the…
3. Reflect on your ideas from question #1 and your data from question #2. How do your observations support, dispute or add to your ideas about what affects how charged bodies interact? My observations support my ideas from question 1. After experimenting with the puck and charges I was able to see how the charges affect the puck by either repelled or attracting it to the charges.…
