Understanding Electric Charges and Fields

Front

What happens to the electric field strength as you move away from a point charge?

Back

The electric field strength decreases as you move away from a point charge.

Front

What is the force between two charges of 3 C and 4 C separated by 2 m?

Back

Front

What is the SI unit of electric charge?

Back

The SI unit of electric charge is the Coulomb.

Front

The electric field lines of a positive point charge:

Back

Point away from the charge.

Front

Which of the following is true about electric charges?

Back

Like charges repel each other.

Front

What is Coulomb's Law?

Back

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

Front

What is the formula for calculating electric field (E) due to a point charge (Q)?

Back

Front

What is the direction of the electric field created by a negative point charge?

Back

The electric field lines point towards the negative charge.

Front

What is the principle of superposition in electric fields?

Back

The principle of superposition states that the total electric field created by multiple charges is the vector sum of the electric fields created by each charge individually.
