1. Two objects suspended by insulating strings attract each other due to static electricity?

a) are they neccessarily oppositely charged?
b) After they are allowed to touch, they continue to attract and need to be pulled away from each other by the strings. Is it possible that both objects are conductors?

2. How can one make an insulating cellulose sphere into a conducting one? ( wrap foil around it?)

3. As a non-conudcting object is being moved toward a charged electroscope E, the leaves of E are falling,
a) Explain which two of the three below are possible for the object and the electroscope:
a.They are of like charge
b. of opposite charge
c. the object is neutral

b) what further simple process/observation must be carried out to differentiate between the two possibliities above?

1.yes on both.

2. correct

3. a,b

If you touch the electroscope, and it was charged, it will discharge. That tells you it was initially charged

for 1 and 3 why though.

1) a) attracted due to opposite charge, therefore yes
b) I do not know why this would happen.

3) why?

1. To answer these questions, we need to understand the concepts of static electricity, charges, and conductors.

a) When two objects suspended by insulating strings attract each other due to static electricity, they do not necessarily have opposite charges. In static electricity, objects can possess either positive or negative charge. If the two objects have the same charge (both positive or both negative), they will repel each other. However, if they have opposite charges, they will attract each other.

b) After the two objects touch and continue to attract each other, it is possible that both objects are conductors. Conductors are materials that allow electric charge to flow through them easily. In this case, the contact between the two objects may have allowed the transfer of charges, resulting in them having the same charge and continuing to attract each other. Conductors can have excess charge on their surface, which redistributes when they come in contact with each other.

2. To make an insulating cellulose sphere into a conducting one, wrapping foil around it can be an effective solution. Foil is a conductor that can provide a pathway for electric charge to flow. By encasing the insulating cellulose sphere with the foil, the electric charge can be transferred between the sphere and the foil, making the sphere conductive.

3. When a non-conducting object is being moved toward a charged electroscope E, and the leaves of E start falling, we can analyze the possibilities:

a) It is possible that both the object and the electroscope are of like charge. If both the object and the electroscope have the same charge, they will repel each other, causing the leaves to diverge and fall.

b) It is also possible that the object and the electroscope are of opposite charge. In this case, the charges on the object and the electroscope will attract each other, causing the leaves of the electroscope to fall.

c) The object can be neutral, meaning it has no net charge. In this case, the object will not influence the charge of the electroscope, and other factors might be responsible for the falling leaves.

To differentiate between the two possibilities mentioned in a) and b), a further simple process can be carried out. One can bring another charged object close to the electroscope. If the leaves of the electroscope attract the second object, it indicates that the first object had an opposite charge. However, if the leaves repel the second object, it indicates that the first object had the same charge as the electroscope.
