Q1. Two large-area parallel metal plates are separated in air by 0.10 mm. If a 1.0 kV potential difference is applied to the plates and an electron is released from the negatively charged plate, what is the electron's maximum velocity? Draw a diagram and show the charges on the plates and the trajectory of electron. (electron charge q = 1.60 x 10-19 C and electron mass = 9.11 x 10-31 kg)

Q2. Two ions are separated by 1.0 x 10-6 m. Ion 1 has two additional electrons (2q excess negative charge) and ion 2 has one missing electron (|q| excess positive charge). Draw a diagram showing the ions on an x-axis with a point "O" midway between them. Calculate the electrostatic potential at O. (q = 1.60 x 10-19 C)
