Why are multiples and sub multiple of s.I unit used |

Answer» Answer: A F
× L ΔL
As the both ΔL and L have same unit i.e. unit of length, so the term L ΔL
will be unit-less. Thus, unit of Young's modulus becomes unit of force divided by unit of area. Therefore, CGS unit of Y is dyne/cm 2 and MKS unit of it is N/m 2 . Thus, 1dyne/cm 2 = (10 −2 ) 2 m 2
10 −5 N
=0.1N (NOTE : 1N=10 5 dyne) |
