Electric potential 0.40 m2 and a plate separation of 0.1 difference of 12 v between the plates? eo a) [4 points) what is the magnitude of the elect a parallel-plate capacitor is made of two parallel plates with - and a plate separation of 0.10 mm. it is then charged so that there is a of two parallel plates with each having a plate area of 12 between the plates? co = 8.85 x 10-12 c2/ n m2, 1.0 mm = 10-3m. s what is the magnitude of the electric field at the point midway between the plates? b) [4 points) what is the charge on each of the plates? c) [6 points) if you want to move an electron from the positive plate to a point midway between the plates, how much work do you need to do? d) [6 points) if an electron is released from rest at a point midway between the plates, da it move toward the negative or the positive plate? calculate the speed with which it will the pla you decide it will move to. electron charge = -e = 1.602 x 10-1°c. electron mass - 9.11 x 10-1kg
