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 moving northwards with a velocity of 10^(7)ms^(-1) in a magnetic field of 3 T,directed downwards.Calculate the instantaneous force on the electron. Given that charge on electron = 1.6 xx 10^-19C

An electron eneters a magnetic field of 5 T intensity with velocity of 5xx10^6ms^-1 at an angle of 30^@ with the field. Find the magnitude of the force acting on the electron.

A monoenergtic electron beam with electron speed of 5.20 xx 10^6 ms^-1 is subjected to a magnetic field of 1.30 xx 10^-4 t normal to beam velocity. What is the radius of the circle traced by the beam, given e/m for electron equals 1.76 xx 10^11 kg^-1 ?

A charge q of mass m moving with velocity v, at right angles to a uniform magnetic field B. Deduce the expression for the radius of the circular path it describes.

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?

An electron moving with a velocity of 10^7 ms^-1 enters a uniform magnetic field of 1 T along a direction parallel to the field. What would be its trajectory in this field?
