Why do the leaves of an electroscope spead apart when a charged object touches the metal knob?
The charged object charges both leaves of the electroscope with like charges and like charges repel.
How do objects become negatively charged using the contact method?
when a negatvely charged object touches a neutrally charged object electrons move to the neutraly charged object making it negativly charged!
When a negatively charged object touches a neutral object does the neutral object gain or lose electrons or protons?
It gains electrons. So if it gains electrons, then the neutral object becomes negatively charged as well.
How does a gold leaf electroscope show that an object is charged?
You know that it is charged if the leaves rise.
How is the charge on a charged object maintained?
If the object remains ungrounded it will remain charged.

Why do the leaves of an electroscope repel each other when a charged object touches a metal knob?
Because when the charged object is say, negatively charged, the electrons in the electroscope want to get as far away as possible from the negative object because "like" charges REPEL. so when the electrons in the electroscope move to the leaves , they now are both negative and "like" charges so now the leaves want to get away from each other as well and that's why they separate.

How does A student puts a negatively charged object against a metal cabinet. Describe what happens to the charge on the object when it touches the metal cabinet?
Well the metal would obviously attract a charged particle for its charge less surface. The only possible way would be placing a positively charged object on the other side of the negative charged object such that it could counter effect the coulombian pull on the negative charge due to the metal. To keep the positive charge in place it would need to place it within oppositely charged electronic plates. This needs more amendments but thats another topic. When a charged object touches metal, the end result is usually what is known as a static shock.
Does a charged object effect an non charged object?
No.
Is static eletricity a very small lightning bolt?
The static electricity isn't. But the little spark you see when an object charged with static electricity touches something else is.
How is the charge on a charged object maintained?
If the object remains ungrounded it will remain charged.
How come the leaves on a metal leaf electroscope repel?
An electroscope detects the static electrical charge on an object. If an object with a electrical charge is touched to the knob on top this charge is transferred to the rod and in turn to the metal leaves in the jar. Opposite charged objects attract and same charged objects repel. The charge on both leaves is the same polarity so they repel each other.
What are some ways in which an object can become charged?
Some ways in which an object can become charged are friction, contact and induction.
