Text Solution
Verified by ExpertsThe correct answer is:
C
Step 1: Understand the definitions of the terms.
Pressure is defined as force per unit area, and in CGS (centimeter-gram-second) units, it is measured in dyne/cm².
Step 2: Stress is also defined as force per unit area (like pressure) and has the same units of dyne/cm².
Step 3: Strain is a dimensionless quantity that represents the deformation of a material and does not have any units; it's simply a ratio of lengths.
Step 4: Young's modulus is defined as the ratio of stress to strain and thus has units of pressure or stress (dyne/cm²).
Therefore, dyne/cm² is not a unit of strain.
