Question

1. Dyne/cm² is not a unit of young modules

​

Answer 1

Answer:

yes it is a unit of Young's modulus in centimetre gram second ( CGS ) .

Explanation:

Generally Young's modulus = stress / strain

so the dimensional formula is only for stress because for strain both the numerator and denominator are cancelled ..So the dimension formula of Young's modulus will be of street that is = Force / Area = Newton /meter square

or the SI unit will be Pascal's

in CGS it is dyne / cm^2.
