# What happens when Unlike charges interact?

And consistent with our fundamental principle of charge interaction, a positively charged object will attract a negatively charged object. In contrast to the attractive force between two objects with opposite charges, two objects that are of like charge will repel each other.
A.

### Why do unlike charges attract?

Two electrons will tend to repel each other because both have a negative electrical charge. Two protons will also tend to repel each other because they both have a positive charge. On the other hand, electrons and protons will be attracted to each other because of their unlike charges.
• #### Do neutrons have a charge?

A neutron, like the name implies, is neutral with no net charge. The charge is believed to be from the charge of the quarks that make up the nucleons (protons and neutrons). A proton is made of two Up quarks, with 2/3 positive charge each and one Down Quark with a negative 1/3 charge (2/3 + 2/3 + -1/3 = 1).
• #### Who discovered that the atom is mostly empty space?

Ernest Rutherford's
• #### How does an object become positively or negatively charged?

Positive and negative charges. Objects can be positively charged, negatively charged or neutral (no charge). A substance that gains electrons becomes negatively charged, while a substance that loses electrons becomes positively charged. Atoms or molecules that become charged are ions.

### How do like charges behave towards each other?

Opposite charges attract each other (negative to positive). Like charges repel each other (positive to positive or negative to negative).
• #### What do objects with unlike charges do?

Two electrons will tend to repel each other because both have a negative electrical charge. Two protons will also tend to repel each other because they both have a positive charge. On the other hand, electrons and protons will be attracted to each other because of their unlike charges.

• #### How do like charges behave towards each other?

Opposite charges attract each other (negative to positive). Like charges repel each other (positive to positive or negative to negative).

### How do opposite charges behave?

A substance that gains electrons becomes negatively charged, while a substance that loses electrons becomes positively charged. When a charged object comes near to another object they will either attract or repel each other. Try clicking the text on the right of this diagram to see how the charges behave.
• #### Do positive and negative charges attract?

We observe in nature that electric charge can come in varying quantities, both positive and negative; and we observe that like charges repel, whereas opposite charges attract. Therefore we must construct a theory which can describe this behaviour.
• #### What are some examples of static electricity?

This is the reason why you sometimes get a shock when you touch your car or another person. Humidity is also a cure against static electricity. The water molecules, which are conductors, can prevent the build-up of excess charge on an object. The most dramatic example of static discharge is a lightning strike.
• #### How can an uncharged object become positively charged?

Some insulating materials become electrically charged when they are rubbed together. A substance that gains electrons becomes negatively charged, while a substance that loses electrons becomes positively charged. Charged objects are able to attract small uncharged objects towards them, such as pieces of paper.
