Young 's modulus of steel is 2.0 xx 10^(...

Young 's modulus of steel is `2.0 xx 10^(11)N/m^(2) `. Express it is `"dyne"/(cm^(2))`.

Text Solution

Verified by Experts

`Y=21xx10^(10)Nm^(-2)=21xx10^(10)" kgm"^(-1)s^(-2)=21xx10^(10)(10^(3)g)(10^(2)cm)^(-1)s^(-2)`
`=21xx10^(11)("g cm s"^(-2))xxcm^(-2)" "therefore" "Y=21xx10^(11)" dyne cm"^(-2)`
