To determine the young's modulus of a wire , the formula is ` Y = (F)/( A) . (L)/ ( Delta l)` , where `L` = l ength ,` A` = area of cross - section of the wire , `DeltaL` = change in the length of the wire when streched with a force `F`. Find the conversion factor to change it from CGS t o MKS system.

Options

A. `1`
B. `10`
C. `0.1`
D. `0.01`

Answer

C

Explanation

`Y = (F)/(A)xx(L)/(Delta L) = ("dyne")/(cm^(2)) = (10^(-5)N)/(10^(-4)m^(2)) = 0.1N//m^(2)`
