Sun is about 330 times heavier and 100 times bigger in radius than earth. The ratio of mean density of the sun to that of earth is

A

`3.3xx10^(-6)`

B

`3.3xx10^(-4)`

C

`3.3xx10^(-2)`

D

`1.3`

Text Solution

Verified by Experts

The correct Answer is:
B
As mass, `M=(4)/(3)piR^(3)rho" or " rho=(3M)/(4piR^(3))`
`:. (rho_(s))/(rho_(e ))=(M_(s))/(M_(e ))xx(R_(e )^(3))/(R_(s)^(3))=330xx((1)/(100))^(3)=3.3xx10^(-4)`.
