Deflected with the earth''s magnetic field if electron gun

Reference no: EM13665202

A TV’s picture-tube faces northward at a place on the Earth where the vertical component of the Earth's magnetic field is 55,000 nano tesla. An Electron gun emits a beam of 12.0 kev electrons toward the screen. How far horizontally is the deflected with the Earth's magnetic field if the electron gun is 20cm from the screen?
