Consider a parallel plate capacitor which is separated by 500 cm and connected to a 135 V power supply, The postive plate has a hole which is small enough so that it doesn not affect the strength or uniformity of the electric eld. An electron is launched vertically into the small hole and reaches a maximum heigh of 35.6 cm (as shown below). Recall the charge and mass of an electron (e : 1 .6UX10'19 C , me : 9.11X1Cl31 kg) Part A Calculate the electric field strength. AEd ? E= N/Cor V/m Submit Request Answer Part B With what initial speed does the electron enter the parallel plate capacitor? ? Un = m/s Submit Request
