The students continued their experiments with chi electrostatics. Joe and Lashonda each blew up a balloon and then
rubbed their dry hair with the inflated balloons. While they did this
the other students notice that their hair was starting to stick straight
out. Next they tied a string to their balloons and let them dangle next
to each other. Predict what will happen.
A)
The balloons will separate because friction has given
each an overall negative charge.
B)
The balloons will move together because the
balloons have gained charge from friction.
C)
The balloons will attract each other because one is
positive and the other is negative.
The balloons have each gained positive charge from
D) friction and like charges attract so they will come
together
