Assertion (A): For a given material, the breaking stress is...

Assertion (A): For a given material, the breaking stress is independent of its length. Reason (R): Breaking stress is the maximum stress a material can withstand before fracturing, and it is an intrinsic property of the material.

Options

  1. ABoth AA and RR are true and RR is the correct explanation of AA.
  2. BBoth A and R are true but R is not the correct explanation of A.
  3. CAA is true but RR is false.
  4. DAA is false but RR is true.

Correct answer

A. Both AA and RR are true and RR is the correct explanation of AA.

Step-by-step solution

Breaking stress is a characteristic property of a material, representing the maximum stress it can endure before breaking, irrespective of its dimensions (length or cross sectional area). Therefore, Assertion (A) is true. Reason (R) correctly explains that breaking stress is an intrinsic property of the material, supporting why it's independent of length.
