tude of each charge is doubled, the force on
each charge is
2. Two charged particles attract each other with 1 F
a force. If the charges of both particles are
doubled, and the distance between them is
also doubled, then the force of attraction will
be
3. Although the energy per coulomb of a the relatively small amount of charge
high-voltage party balloon is high, the energy
transfer that occurs if you touch it is low due
to
