A uniform charge of Q is placed on the sphere of a Van de Graaff generator, such that electron discharge is observed from a conducting point a distance of 46 cm away (center to center).

Let the dielectric strength of air... E = 3 x 10⁶ N/C

a) Determine the Electric Potentials at the 80 cm and 50 cm radial locations:

b) A small air balloon of charge q = - 8.4 nC and mass 1.52 grams, is placed at rest at the 80 cm potential surface and then released. Determine its speed v at the 50 cm radial location: {neglect any air resistance)

hint: Work-Energy Theorem... W = delta K
