Front

The law, governing the force between electric charges is known as

Back

Coulomb's law

Front

How can a body be negatively charged?

Back

Giving excess of electrons to it

Front

Which two particles are attracted to each other?

Back

A proton and an electron

Front

A repulsive force exists between which two particles?

Back

Two protons

Front

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

Back

The attractive force increases

Front

What happens to the electric force between two charges when the distance is tripled?

Back

9 times less electric force

Front

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

Back

Negatively charged particles move from head to balloon

Front

Coulomb's law says that the force between any two charges depends

Back

Both directly on the size of the charges and inversely on the square of the distance between the charges.
