The charge will spread out evenly across the balloon's surfaces and the balloon will drift towards the charged rod.
The charge will spread out evenly across the balloon's surfaces and the balloon will drift away from the charged rod.
The charged region of the balloon will not move. Instead the balloon will rotate towards the charged rod and drift towards it.
The charged region of the balloon will not move. Instead the balloon will rotate away from the charged rod and drift away from it.

18 When a battery stops working, we say it is "dead." A battery is dead when...
...all the charges have moved from one side of the battery to the other.
...all the charges in the battery have given up ALL of their energy some kind of consumer such as a light bulb.
...the battery runs out of energy.
19 An electron is placed between 2 plates connected to a 22 volt battery. The electron feels a force of 1.6 x 10-18 N. Which set of given is listed correctly?
v = 22 V, F = 1.6 x 10-18 N, E = 1.6 X 10 -19 N /C
v =22 V, F= 1.6 X 10-19 , E = 1.6 x 10-18 N /C
v = 1.6 x 10-18 V, E = 1.6 x 10-18 N /C , q = 1.6 x 10-19 C
v = 22 V, F = 1.6 x 10-18 N, q = 1.6 X 10 -19 C
v = 22 V, F = 1.6 x 10-18 N, q = 1 eV
