Answer:
Thomson's experiments with cathode ray tubes showed that all atoms contain tiny negatively charged subatomic particles or electrons. Thomson's plum pudding model of the atom had negatively-charged electrons embedded within a positively-charged "soup."
Answer:
Induction
Explanation:
When a body is brought in contact with another, electrons are rearranged by contact.
When a body is rubbed against one another, charging by friction occurs.
The process whereby electrons are rearranged without direct contact with one another is called induction.
By induction electrons can get charged without them having to be in contact with one another.
- When a charged body is brought to the vicinity of the electrons, either an attraction or repulsion force is set up.
- Similar charges causes repulsion
- If a negatively charged body is brought near the electrons, there would be heavy repulsion and the electrons would be forced to rearranged.
- This effect is product as a result of a force field.
