Question

QUESTION 2 (10 MARKS) An electric point charge is fixed in place 0.70 m above a very large, negatively charged flat plate as shown in the figure. The point charge has magnitude +10"C and the electric field magnitude generated by the plate is 1000 Vim. Ignore gravity in what follows. y-axis Point charge : 0.70 m Negatively chargod pac Make a drawing of the electric field vectors due to both charge distributions (plate and point) along a straight line parallel to the y-axis and passing through the point charge, in the following three regions: above the point charge, in between the plate and the point charge, and under the plate (i.e. six vectors in total). a) In which of the three regions in a) can the electrostatic force NEVER be zero along the y-axis? b) Calculate the potential difference between two locations on the y-axis, at ya = 1.6 m and y,-1,1 m above the charged plate if you are c) i) considering the charged plate only i) considering the point charae onls Chint what are the distances fom the point charge 12) to the locations?) iii) Then calculate the the work done by the field in moving a charge of10"C from etwo locations, between these two locations, and hence
