state all final values in SI units to the correct number of significant figures. Draw a diagram for every question, label as required. Clearly show the key equation for each question and in words, describe any principles you've used. The marking rubric for this assignment is available to view in topic - Electric Potential & Electric Fields

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)
