Static Electricity

1. An insulator is a material that ________ charges to move freely, and a conductor is a material that ________ charges to move freely.

- Answer:
An insulator is a material that does not allow charges to move freely, and a conductor is a material that allows charges to move freely.

- Explanation:
Insulators have tightly bound electrons, which do not move easily when an electric field is applied. Examples include rubber, plastic, and glass. Conductors, on the other hand, have loosely bound electrons that can move freely under the influence of an electric field. Examples include metals like copper and aluminum.

2. Charged objects ________ neutral objects.

- Answer:
Charged objects attract neutral objects.

- Explanation:
When a charged object (either positively or negatively charged) is brought near a neutral object, it induces a separation of charges in the neutral object. This causes the neutral object to be attracted to the charged object due to the induced opposite charge on its surface.

3. There are ________ types of charges. They are ________ and ________ charges.

- Answer:
There are two types of charges. They are positive and negative charges.

- Explanation:
In static electricity, there are two fundamental types of electric charges: positive and negative. These charges are defined based on their interaction:
- Positive charges are represented by protons.
- Negative charges are represented by electrons.

4. The symbols for these charges are ________ for positive and ________ for negative.

- Answer:
The symbols for these charges are + for positive and - for negative.

- Explanation:
By convention, positive charges are denoted by the symbol +, and negative charges are denoted by the symbol -.

5. Like charges ________, and opposite charges ________.

- Answer:
Like charges repel, and opposite charges attract.

- Explanation:
According to Coulomb's Law:
- Charges of the same type (like charges) repel each other.
- Charges of opposite types (opposite charges) attract each other.

6. A positive charge will ________ another positive charge, and ________ a negative charge.

- Answer:
A positive charge will repel another positive charge, and attract a negative charge.

- Explanation:
- A positive charge repels another positive charge because like charges repel.
- A positive charge attracts a negative charge because opposite charges attract.

7. A negative charge will ________ another negative charge and ________ a positive charge.

- Answer:
A negative charge will repel another negative charge and attract a positive charge.

- Explanation:
- A negative charge repels another negative charge because like charges repel.
- A negative charge attracts a positive charge because opposite charges attract.
