An electron beam is deflected by 1.76 mm in travelling a distance of 10 cm through an electric field of 1,800 V`m^-1` acting perpendicular to its path. Find the electron chawrge to mass ratio, if average velocity of the electrons is `3xx10^7ms^-1`

An electron is projected with a velocity of 10^5 ms^-1 at right angles to the magnetic field of 0.019 G. Caclculate the radius of the circle described by the electron.

An electron is released with a velocity of 5xx10^6ms^-1 in an electric field of 10^3NC^-1 which ahs been applied so as to oppose it motion. What distance would the electron travel and how much time could iyt take before it is brought to rest?
