Note of Mechanics Class 12
This handwritten note of Mechanics contains following topics which are important in NEB examination.- J.J Thomson's Experiment
- Experimental determination of specific charge of electron (e/m)
- Millikan's oil drop experiment
- Experimental determination of charge of electron
- Einstein's Photoelectric equation
- P-N diode as a half wave rectifier.
- P-N diode as a full wave rectifier.
- Zener diode as a voltage regulator.
Working Principle of J.J Thomson's Experiment
The experimental setup consists of low voltage supply, filament (F) glass tube, cross field (electric and magnetic field), slit, fluorescent screen as shown in figure.
The low voltage supply heats the filament (F) and electrons are ejected from Filament. They are accelerated toward cross field. The electron strike S when both fields are not applied and finally they strike S when cross field is applied.
The workdone on electron is equal to Kinetic energy gained by electron.
