1.	Electron, initially almost at rest, are accelerated by a potenetial difference of `200` volt. They then pass through an electric field and a magnetic field at right angle to each other and also at right angles to the electron beam. The magnitudes of two fields are so adjusted that the electrons emerge out straight without any deviation. Determine the specific charge, if the electric field is `1117.6` volt `cm^(-1)` and magnetic field is `14` gauss.
