electrons are emitted with negligible speed from a plane cathode in an evacuated tube .the electrons are accelerated towards a plane anode which is parallel to the cathode and 2.0cm from it by a potential difference of 1000v. find the time taken for an electron to move from the cathode to the anode. ( specific charge of electron e/me = 1.8×10 ^11 c/kg)?
