(a)
Interpretation: Whether the given statement is true or false needs to be determined.
Concept Introduction: Theory is a group of connected ideas or concepts intended to describe something. It involves question- “why” or “how anything/ somethings happens. It is based on inference.
(a)
Answer to Problem 17A
The given statement is false.
Explanation of Solution
Scientist J.J. Thompson proposed a different model of an atom. Thomson knew that objects with similar charges resist or repel each other. Excluding this he also, knew that objects with different charges attract each other. Cathode rays (electrons) don’t depend upon the substantial of electrons and also, on the nature of gas present in the CRT (cathode ray tube). In his CRT experiment, J. J. Thomson obtained that beams of identical particles (or units) whose nature didn’t depend on what metal was used to produce or generate them. So, the given statement is false.

(b)
Answer to Problem 17A
The given statement is true.
Explanation of Solution
Scientist J.J. Thompson proposed a different model of an atom. In J.J. Thomson’s atomic theory, electrons are distributed inside a positive mass like raising in a plum pudding. According to the J.J. Thomson’s atomic theory, tiny negative electrons were distributed in a positive (+ve) mass inside the atom. The electrons were like negative (-ve) raising in a positive (+ve) plum pudding dough. So, the given statement is true.

Also, atomwas envisioned like a sphere of positive charge(+ve) in which, negatively charged(-ve) electrons were uniformly distributed. So, the given statement is false.
