15 An oil-drop, that has a mass of 3.5 x 10 kg and an excess of 7 electrons, is located between horizontal parallel plates. The plates are separated by a distance of 2.5 cm and have and potential difference of 4.8 x 102 V between them. Positively charged plate Charged Particle Plate separation = 2.5 cm Negatively charged plate Draw the electric field lines showing the electric field direction and shape between the parallel plates above. (1 mark) Determine the magnitude and direction of the acceleration on the charged particie. (4 marks) Name: Describe one change that could be made to the above experiment so that the charged particle will be now be suspended. Explain how the change will allow the particle to be suspended and justify your answer with appropriate formulas (3 marks) Rough Pore Determine the time required for the particle to move from the upper plate to the lower plate when the particle begins at rest. (2 marks) Ground State 15 An oil-drop, that has a mass of 3.5 x 10 kg and an excess of 7 electrons, is located between horizontal parallel plates.
