FAQs

1. What is the principle behind the e/m apparatus by Thomson’s method?

The apparatus works on the principle of deflecting an electron beam using perpendicular electric and magnetic fields, allowing the calculation of the electron’s charge-to-mass ratio based on the deflection observed.

2. Is this apparatus compatible with standard lab power supplies?

Yes, the e/m apparatus is designed to work with standard DC power supplies commonly found in physics laboratories, ensuring seamless integration into existing setups.

3. Are there any alternatives to Thomson’s method for measuring e/m?

Alternative methods include using a fine-beam tube or mass spectrometers, but Thomson’s method remains a classic and widely taught approach due to its simplicity and educational value.

4. How should the e/m apparatus be stored when not in use?

Store the apparatus in a dry, dust-free environment, preferably in its original packaging or a protective case to prevent damage to the glass components and ensure long-term accuracy.

5. What safety precautions should be taken while using this apparatus?

Always ensure the power supply is properly grounded, avoid touching live components, and handle the glass tube with care to prevent breakage. Use in a well-ventilated area if high voltages are involved.
