1. A voltage of 13 V is applied across the ends of a piece of copper wire 8 cm long. The mass of an electron is 9.11 × 10−31 kg and its charge is 1.6 × 10−19 C.
What is the magnitude of the electron’s acceleration?
Answer in units of m/s2.
2. After traveling 3 × 10−8 m, if it does not collide with a copper ion over this distance, what is the kinetic energy of the electron? Answer in units of eV.
