Q8b (2 points) b) Another negatively charged particle is moved into the field generated by a positively charged plastic strip. Describe how the force changes as the negatively charged particle is moved closer to the positive charge. (2 marks)a) A small negatively charged particle is accelerated from the negative to the positive plate where there is a potential difference of 2500 V. i) Calculate the distance between the plates, if the field strength is 7200 Vm 1 (2 marks) ii) Calculate the charge on the particle if the particle gains 1.2 x 10"15 Joules of energy. (3 marks) fil) Is this energy potential or Kinetic energy? (1 mark)
