Use the following information to answer the next question.
An oil-drop, that has a mass of \( 3.5 \times 10^{-15} \mathrm{~kg} \) 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 \( 4.8 \times 10^{2} \mathrm{~V} \) between them.
Positively charged plate
Charged Particle
Plate separation \( =2.5 \mathrm{~cm} \)
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 particle. (4 marks)
