Assignment Complete the following assignment and submit your work to the dropbox. Before you upload your file, ensure your name appears in the file name. Be sure to provide explanations to ensure maximum part marks. 1. In a hydrogen atom, the electric force is the centripetal force. Determine speed of an electron in orbit around a proton if the distance between them is 5.29 x 10-¹1 m. The mass of an electron is 9.11 x 10-31 kg. 2. A charge with a value of 2.2 x 10-6 C is placed 12 cm to the left of a 3.8 x 10-6 C charge. At what point between the charges should a test charge be placed so that it experiences no net electric force? 3. Determine the magnitude of the electric field 0.75 m from a 0.63 C master charge. What would be the force on a 0.50 C test charge placed here? 4. A drop of oil is floating between two parallel plates with a separation of 8.3 mm. If the mass of the oil drop is 2.7 x 10-15 kg, and its charge is -9.612 x 10-19 C, determine the voltage across the charged plates and determine which plate is positive.
