Two negatively-charged balloons with a mass of 1.78 g are suspended by threads from a common point on the ceiling. The two balloons repel to an equilibrium position in which the angle between the two threads is 13.1 degrees. The distance from ceiling to the center of either one of the balloons is 155 cm. Determine the charge on each balloon. Assume the same amount of charge is on each balloon.
Two identical spheres are attached to silk
threads of length L=0.60 m and hung from a
common point as shown in the figure. Each
sphere has a mass m=7.0 g. One sphere is
given a charge q1, and the other is given a
different charge q2, this causes the spheres
to separate so that when the spheres are in
equilibrium, each thread makes an angle □
= 20 degrees with the vertical. A small wire
is then connected to the spheres, allowing
charge to be transferred from one sphere to
the other until the two spheres have equal
charges, the wire is then removed. Each
thread now makes an angle = 30 degrees.
Determine the original charge (in micro-
coulomb) of q1."
