Which of the following statement is incorrect?

A Classical Physics deals with macroscopic phenomena and includes subject like mechanics, electrodynamics, optics and thermodynamics.
B All Physics and also mathematics is based on assumptions each of which is variously called hypothesis or axiom or postulate etc.
C A hypothesis is a supposition with asstuming that is true.
D An axiom is a self-evident truth, while a modei is a theory proposed to explain observed phenomena.

Verified Solution

Answer & Solution

Correct Answer

(C) A hypothesis is a supposition with asstuming that is true.

Step-by-step Solution

Detailed explanation

Classical physics is indeed concerned with macroscopic phenomena, encompassing mechanics, electrodynamics, optics, and thermodynamics, making the first statement correct. Physics and mathematics are built upon foundational assumptions known as hypotheses, axioms, or postulates,…

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
