Young's modulu of steel is 1.9xx10^(11) ...

Young's modulu of steel is `1.9xx10^(11) N//m^2` When expressed is CGS units of `dy"nes"// cm^2` it will be equal to `(1N = 10^5dy"ne", 1 m^2 = 10^4 cm^2)`

A

`1.9xx10^(10)`

B

`1.9xx10^(11)`

C

`1.9xx10^(12)`

D

`1.9xx10^(13)`

Text Solution

Verified by Experts

The correct Answer is:
(c )
Here, `Y = 1.9xx10^(11) N//m^2 = 1.9xx10^(11) xx(10^5dyne)/((10^2cm)^2) = 1.9xx10^(12)"dyne"//cm^2`.
