Coulombs Law and Charge

Front

What is Coulomb's Law?

Back

Coulomb's Law states that the force between two charged objects 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 happens to the force between two charged objects if you double the distance between them?

Back

The force decreases to 1/4 of its original value.

Front

If the charge of one object is tripled, how does the force change?

Back

The force increases by a factor of 3.

Front

What is the formula for calculating the force between two charges?

Back

F = k * |q1 * q2| / r^2, where F is the force, k is Coulomb's constant, q1 and q2 are the charges, and r is the distance between them.

Front

What is the value of Coulomb's constant (k)?

Back

Coulomb's constant (k) is approximately 8.99 x 10^9 N m²/C².

Front

What is the effect of like charges on each other?

Back

Like charges repel each other.

Front

What is the effect of opposite charges on each other?

Back

Opposite charges attract each other.

Front

Calculate the force between two charges of 1 C each, 1 m apart.

Back

F = 8.99 x 10^9 N.

Front

What happens to the force if both charges are doubled?

Back

The force increases by a factor of 4.

Front

If two charges are 0.5 m apart, how does this affect the force compared to when they are 1 m apart?

Back

The force increases by a factor of 4.
