Solution - An Electron Gun with Its Collector at a Potential of 100 V Fires Out Electrons in a Spherical Bulb Containing Hydrogen Gas at Low Pressure (∼10−2 Mm of Hg) Determine E/M From the Data. - Photoelectric Effect and Wave Theory of Light

ConceptPhotoelectric Effect and Wave Theory of Light

Question

An electron gun with its collector at a potential of 100 V fires out electrons in a spherical bulb containing hydrogen gas at low pressure (∼10−2 mm of Hg). A magnetic field of 2.83 × 10−4 T curves the path of the electrons in a circular orbit of radius 12.0 cm. (The path can be viewed because the gas ions in the path focus the beam by attracting electrons, and emitting light by electron capture; this method is known as the ‘fine beam tube’ method. Determine e/m from the data.
