1. Consider a cylindrical wire that has conduction electron density 6.0 × 1028 4 and radius 0.5 mm. An electric field with strength m 7.5 x 10-4 creates a current of 4.8 × 10'' electrons per second. C a) What is the average drift speed for an electron? (include units) b) What is the average time in between electron collisions? fs (express your answer in femtoseconds)
