An Electron is emitted by heating a cathode and is accelerated by the potential difference between the anode and a cathode. The electron emerges out from the anode with velocity 2.3x10 m/s. Find the velocity (in m/s) of the electron when it comes out of the parallel plates at a PD of 800 V. Use x = 0.17 m and y = 0.09 m. 800 V Cathode Anode уу 1 electron beam OV Give your answer in scientific representation rounded off to two decimal places. (Remember that 2.97x108 = 2.97E8 in moodle) Select one: O A. 2.44 OB. 1.15e7 O C. 2.30e6 OD. 2.89e5 O E. 1.15e8
