FLASHCARD QUESTION

Front

What is Coulomb's Law?

Back

Coulomb's Law describes the force between two charged objects. It states that the force is directly proportional to the product of the magnitudes of the charges and inversely proportional to the square of the distance between them.

2.

FLASHCARD QUESTION

Front

What happens to the force between two charges if the distance between them is halved?

Back

The force between the charges quadruples because force is inversely proportional to the square of the distance.

3.

FLASHCARD QUESTION

Front

Define charging by conduction.

Back

Charging by conduction occurs when two objects with different charges come into direct contact, allowing electrons to transfer from one object to another.

4.

FLASHCARD QUESTION

Front

What is the effect of a negatively charged object on nearby neutral objects?

Back

A negatively charged object can induce a charge separation in nearby neutral objects, causing electrons to be repelled and creating a positive charge on the side closest to the negative object.

5.

FLASHCARD QUESTION

Front

Explain the concept of electric field.

Back

An electric field is a region around a charged object where other charged objects experience a force. The strength and direction of the field can be represented by field lines.

6.

FLASHCARD QUESTION

Front

What is the principle of superposition in electrostatics?

Back

The principle of superposition states that the total force acting on a charge due to multiple other charges is the vector sum of the individual forces exerted by each charge.

7.

FLASHCARD QUESTION

Front

What is the relationship between charge and electric force?

Back

The electric force between two charges increases with the amount of charge and decreases with the square of the distance between them.
