A contact-charged electroscope and the charging object have the opposite charge.

Question

A contact-charged electroscope and the charging object have the opposite charge. True or False? Explain. An induction-charged electroscope and the charging object have opposite charge. True False? Explain. A positively charged glass rod attracts a suspended object. Can we conclude that the suspended object is negatively charged? Explain. A negatively charged rubber rod attracts a suspended object made of an insulating material. Can we conclude that the suspended object is positively charged? Explain. A person standing on an insulated stool touches a charged copper rod suspended by an insulating string. Does the conductor become completely neutral? Explain.

Explanation / Answer

1)

False :- Because it has the same charge at the rod, not opposite.

2)

True :- It would have opposite charge, charge is pulled for the body to neutralized the charge, which is turn changes,

the charge from positve to negative and vice versa.

3)

We can not conclude that it has an opposite charge because it could be opposite or it could be neutral.

4)

No, could still have the pulverising effect and object could be positive or neutral.

5)

It will be effectively neutral, but not completely neutral the charge is conserved it has to go somewhere with in the

system. your body act as a charge reservior and absorbs some charge from the system.
