Friction will give a positive charge to a neutral object by conduction. This is done by rubbing two different materials together.

What kind of charge can move from object to object?
Electrons can move from object to object. Electrons have a negative charge. So if an object is determined to have a positive charge, then some of the electrons have moved from the object to somewhere else. Something with a neutral charge has the same number of electrons [-] and protons [+]. If electrons [-] leave, then there will be more protons, and a net positive charge. If an object gains electrons, then the object has a net negative charge.
If a neutral object loses negative charge what will the net force be?
If a neutral object loses negative charge, then all we can say is that the objectwill be positively charged. We don't know anything about force until we knowhow much net positive charge it has, what othercharged object is in theneighborhood, what the size and sign of thatone's charge is, and the distancebetween the two objects.
Does iron have a positive charge?
yes of course it does, iron has a +1, +2, +3, and a +4 charge
How does body becomes negatively charge?
It gains electrons. The only charged particles which can freely move from one object to another are electrons. Electrons have negative charge. So adding electrons gives a negative charge, and removing electrons gives the object a positive charge.
What can you say about the number of protons and electrons on a neutral object?
The numbers of protons and of electrons in a neutral object are the same.
How can an object have a neutral charge if part of the object has a positive and a negative charge?
If the positive and negative charges are equal, then the object has a 'net' neutral charge.
Do positive and neutral attract each other?
both positive and negative objects attract to neutral object so yes positive and neutral will attract each other.
An electrically neutral object can be attracted by a positively charged object because?
A neutral pith ball is still "charged", it just doesn't display excessively charged behavior. Since it is neutral, having nearly equal positive and negative charge, the proximity of the positively charged pith ball still attracts the negative charge present in the ball, inducing polarization moving the ball closer to the positively charged one. Once they make contact, the conductibility of the pith ball quickly accepts excess charge from the other, creating a like charge repulsion.
Is an object that has no electric charge as a whole is negative or positive?
No. It is neutral.
What is the overall charge when an atom has more protons than electrons?
It has a positive charge.
When there is an equal amount of positive and negative charges on an object what is the object?
As equal amount of positive and negative charges are there then the net charge on the object is the algebraical sum of them and hence it becomes zero. So chargeless.
What are the charges of electricity?
An electrical charge can be one of two opposites, which are traditionally called "positive" and "negative". If there is no charge on an object, the object is said to be "neutral".
What objects with equal amounts of positive and negative charge are said to be electrically?
An object with equal amounts of positive and negative charge is electrically neutral.
Why is a neutral object attractred to a charged object?
This is known as electrostatic induction. As charged object (say positive) is brought near by the neutral object the opposite charges i.e. negative would get attracted towards and positive charges would be pushed away. Yet the object is neutral though the charges got separated. Now due to attraction of unlike charges the neutral is attracted towards the charged one.
What is the charge of an object that has an equal number of protons and electrons?
Yes, protons always have a positive charge.
What object has neither a positive or negative charge?
When an object has 'no' charge, it is neutral.
Does a neutral object repel a positive object?
No. The actual result is the opposite. If a charged object is brought into the vicinity of a neutral object, normally the two objects attract. The attraction is a consequence of polarization. A neutral object is still composed of many charges associated with the electrons and nuclei of the atoms of the object. If it is a conductor, then electrons will easily move around the conductor in an electric field, but even a nonconductor allows some small movement of the electrons of the atoms. In either case, the movement is such that the electrons in the neutral object tend to shift opposite to the direction of any applied field, i.e. towards a positive charge if a positive object causes the field or away from a negatively charged object. For a neutral object, "polarization" is the charge separation on the object that is caused by the external electric field, for instance a nearby negative object. (Polarization is, by definition, the charge separation induced by an external field and this is a materials property that is different for different materials.) When that charge separation takes place, the electrons (negative) will move somewhat away from a negative object nearby and leave a net positive on the part of the neutral object closest to the negative object. The neutral object has equal amounts of positive and negative charge, but the exposed positive charge is closer to the negative object and thus feels a greater force. There is both an attractive force and a repulsive force acting on different regions of the neutral object, but attraction always is greater because the region experiencing the attraction is closest to the external charge causing the polarization.) In general, a charge (positive or negative), brought near a neutral object will result in polarization of the neutral object and an attractive force between the two object. Polarization forces are larger when the neutral object is a conductor, but for nonconducting materials it is smaller and depends on the type of material.
