//Multiple Choice

Which of the following is a property of electric charge? {
    ~Mass
    ~Volume
    =Attraction and Repulsion
    ~Color
}

The SI unit of electric charge is\: {
    ~Ampere
    =Coulomb
    ~Volt
    ~Ohm
}

If two objects have the same type of charge, they will\: {
    ~Attract each other
    =Repel each other
    ~No effect
    ~First attract, then repel
}

The charge of one electron is approximately\: {
    =1.6×10-19 C
    ~9.8× 10-19 C
    ~1.6× 10-15C
    ~9.5×10-19
}

Which law governs the force between two point charges? {
    ~Newton’s Law
    ~Ohm’s Law
    =Coulomb’s Law
    ~Faraday’s Law
}

//True or False

Protons are negatively charged particles. {F}

An atom has equal numbers of protons and electrons. {T}

Coulomb's law explains the gravitational force between two masses. {F}

A neutron has no charge. {T}

Opposite charges repel each other. {F}

//Fill in the blanks
