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 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!
Would a negatively charged balloon stick to a metal rod?
No. It is not possible. Because as soon as balloon touches the metal charges would be conducted.
What are some examples of charging by contact?
When a charged object touches another object. Electrons can be transferred through friction. Electrons can also be transferred through contact and conduction. You can charge a neutral object by contact with a charged object. Charging by contact happens when electrons move from one object to a neutral object.
Why must a sphere rod and leaves of an electroscope be a conductor?
When a negatively charged rod touches the sphere of the electroscope, negative sharge spreads throughout the metal. Since the leaves are both negatively charged, the free ends repel and move away from each other. When a positvely rod touchs the sphere, negative charges move toward the sphere, causing the leaves to be positively charged. hope this helps :)

It gains electrons. So if it gains electrons, then the neutral object becomes negatively charged as well.
If a negatively charged polyethylene strip touches a neutral pith ball what charge will it have?
the pith ball takes on a negative charge also, the charge transfers to the pith ball from the strip

What happens when you bring a negatively charged rod near a piece of metal.?
protons in the metal move toward the rod.

What do you do when neutral water touches your skin?
nothing
Is the test light supposed to light up when you use the ground from the battery or only light up from the positive side?
If the alligator clip from the test light is attached to the negative post of the battery it will light up whenever the probe end touches a positively charged circuit and likewise if the alligator clip is attached to the positive terminal of the battery the test light will light up when the probe end touches a negatively charged circuit
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.
Why do leaves of gold leaf electroscope expand when a charged body touches it?
They both get charged with the same polarity, and therefore repel each other.
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.
