Q1. The wire is made up of atoms with valence 2 and molecular mass 80 g/mole, where u = 1.5605 × 10-27 kg is the mass of a hydro- gen atom. Assume there is one conduction electron per atom.

What is the drift speed of the electrons when there is the voltage drop of 94.5 V across wire?

Q2. Two charges, and are the distance apart. These two charges are free to move but do not because there is a third charge nearby what should be the magnitude of the third charge and its placement in sequence for the first two to be in equilibrium?
