Question

A point charge q sits at the center of a hollow metal sphere as shown above, where the inner radius is a = 10.0 cm and the outer radius is b=16.0 cm. There is +5.80 nC distributed on the inner surface of
the sphere, and -19.0 nC on the outer surface. If an electron is placed at a distance of 24.0 cm from the centre of the sphere, and released from rest, what is its inital acceleration?

You have a summer job in the Exploratorium in San Francisco. Your team has been tasked to make an exhibit where a small charged pith ball is levitated above a large charged plate with a small circular opening in the middle. The pith ball is to be suspended about 5 cm above the center of the circular opening. After sufficient testing, you know that the plate could be roughly uniformly charged with 2.5 µC/m?. You measure 9.6 cm for the diameter of the circular opening and 0.20 grams for the mass of the pith ball. Find what the charge on the pith ball should be.
