Final answer:
A point charge q of mass 8.50 g hangs in static equilibrium, with the weight of the charge balanced by the tension in the string.
Step-by-step explanation:
A point charge q of mass 8.50 g hangs. This scenario can be described as an example of static equilibrium.
In static equilibrium, the net force acting on the charge is zero. The weight of the charge is balanced by the tension in the string, and the charge remains stationary.
To analyze the scenario further, we need additional information such as the charge of the point charge and the properties of the string.
