Electrical Force & Charge Assignment

Front

What is the charge of a proton?

Back

Positive

Front

What happens when an atom gains one or more electrons?

Back

It becomes a negative ion.

Front

In Coulomb's Law, how does the force between two charged objects change if the distance between them triples?

Back

It becomes one-ninth as strong.

Front

Which of the following is NOT true about electrical forces compared to gravitational forces?

Back

Gravitational forces are always attractive.

Front

What is the fundamental charge (the charge of an electron)?

Back

1.6 × 10⁻¹⁹ C

Front

What is the charge of an electron?

Back

Negative

Front

What is an ion?

Back

An atom or molecule that has a net electric charge due to the loss or gain of one or more electrons.

Front

What is Coulomb's Law?

Back

A law stating that the force between two charged objects is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.

Front

What is the unit of electric charge?

Back

Coulomb (C)

Front

What is the relationship between electric force and distance?

Back

Electric force decreases as the distance between charges increases.
