In MKS system, Stefan's constant is denoted by `sigma`. In CGS system multiplying factor of `sigma` will be

A

1

B

`10^(3)`

C

`10^(5)`

D

`10^(2)`

Text Solution

Verified by Experts

The correct Answer is:
B

In MKS system, unit of `sigma` is (`/(m^(2)xxsec xx K^(4))`
`rArr J/(m^(2) xx sec xx K^(4))= (10^(7)erg)/(10^(4)cm^(2) xx sec xx K^(4))=10^(3)(erg)/(cm^(2) xx sec xx K^(4))`
