Thompson CRT Experiment

What tool was thomson using in his experiment

• Microscope

• Magnets

• Cathode ray tube

• Both magnets and cathode ray tube

Thomsons atomic theory proved that the stream in cathode ray tube is made of small particles which is piece of the atom and is

• Neutral

• Negatively charged

• Positively charged

• Both negative and positively charged

What base principle was used in the cathode ray experiment

• Oppositely charged particles deflect each other

• Likely charged particles attract each other

• Oppositely charged particles attract each other

• None of these

What was the cathode ray tube

• A glowing glass tube

• A high vacuum tube in which cathode rays produce a luminous light

• A beam of electrons emitted from a cathode

• None of the above

What did Thomson prove was wrong in daltons atomic theory

• There were protons

• There were negatively charged particles

• Protons are positively charged

• There were neutrons

Thompson's experiments provided evidence that

• atoms contain a positively charged nucleus

• atoms are made of smaller "sub-atomic" particles

• atoms are solid spheres with different masses

• Atoms are particles that cannot be divided

What was the main discovery of Thomson's CRT experiment?

• Electrons are negatively charged particles

• Protons are positively charged particles

• Neutrons are neutral particles

• Atoms are indivisible

Which component did Thomson use to deflect the cathode rays in his experiment?

• Electric field

• Magnetic field

• Both electric and magnetic fields

• Gravitational field

• Cathode rays are neutral

In Thomson's experiment, what was the purpose of the cathode ray tube?

• To generate light
