Coulomb's Law - Extra practice

Which two particles are attracted to each other?

• Two neutrons

• A proton and an electron

• Two protons

• An electron and a neutron

A repulsive force exists between which two particles?

• Two neutrons

• An electron and a neutron

• An electron and a proton

• Two protons

As two oppositely charged particles get CLOSER, what happens to the electrical force between them?

• The attractive force increases

• The attractive force decreases

• The repulsive force increases

• The repulsive decreases

A balloon is rubbed on a student's head. What occurs because of this?

• Charged particles on the balloon are destroyed

• Protons move from head to balloon

• Charged particles from the balloon are released into the air

• Electrons move from head to balloon

There is MORE electric force when charges are...

• close together
• far apart
• the electric force stays the same

What variable is measured in Coulombs (C)?

• Charge (q)

• Force (F)

• Distance (d)

• Mass (m)

If there's MORE charge (q), what happens to the force?

• MORE force

• LESS force

• Force is not affected by charge (q)

If there's MORE distance between charges, what happens to the force?

• MORE force

• LESS force

• Force is not affected by distance

What variable is measured in Newtons (N)?

• Electrostatic Charge
• Force
• Distance
• Mass

If there's LESS charge (q), what happens to the force?

• LESS force

• MORE force

• Force is not affected by charge
