Two identical balloons are inflated and charged in the same manner.
They are tied by threads and hung from the same pivot point on the
ceiling. The balloons hang down, with the threads making an angle
of 14° with each other and the balloons being separated by a
distance of 58 cm (center-to-center). Each balloon has a charge of -
3.5x10-7 C. Draw a free-body diagram for the balloons and consider
them to act as point objects.
You have a lightweight spring whose unstretched
length is 4.0 cm. First, you attach one end of the
spring to the ceiling and hang a 2.2 g mass from it.
This stretches the spring to a length of 4.9 cm .
You then attach two small plastic beads to the
opposite ends of the spring, lay the spring on a
frictionless table, and give each plastic bead the
same charge. This stretches the spring to a length
of 4.4 cm .
Part A
What is the magnitude of the charge (in nC) on each bead?
Express your answer in nanocoulombs.
