Electric Charge and Coulomb's Law

A body can be negatively charged by:

• Giving excess of electron to it

• Removing some electron from it

• Removing some neutron from it

• Giving some protons to it

As two oppositely charged particles approaches each other, what happens to the electrical force between them?

• The magnitude of the electrical force decreases

• The magnitude of their charges increases

• The attractive force increases

• The repulsive force incresaes

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

• Charged particles on the balloon are destroyed

• Charged particles from the balloon are released into the air

• Positively charged particles move from head to balloon

• Negatively charged particles move from head to balloon

The law governing the force between electric charge is known as:

• Ampere's Law

• Coulomb's Law

• Gravitational Law

• Faraday's Law

When distance increases, electrostatic force ________; we call this relationship ________ proportional

• decreases; directly

• increases; directly

• decreases; inversely

• increases; inversely

The Electric Force is strongest when charges are:

• close together

• the electric force is constant everywhere

• far apart

• none of the above
