Name:
Two identical balloons, each having
a mass m of 1.0 g, are suspended at the end of a 60 cm long
thread (see figure). The balloons are then vigorously rubbed with a rabbit fur and each acquires
charge q. They hang in equilibrium with a distance of 30 cm between their centers. Determine the
charge q on each balloon.
