An Electron is emitted by heating a cathode and is accelerated by the potential difference of V volts between the anode and a cathode. The electron emerges out from the anode with velocity of 4 x 107 m/s. Find height h gained by the electron while leaving the parallel plates. Use x = 0.17 m and y = 0.05 m. 800 V Cathode Anode clectron beam
