In a cathode ray tube a potential difference of `3000` volt is maintained between the electrodes `2 cm` apart. A magnetic field of `2.5xx10^(-4) Wb//m^(2)` at right angles to the electric field gives no deflection of the electron beam which received an initial acceleration by a potential difference of `1000` volt. Calculate `e//m`.
