The ratio of weights of two sphere of di...

The ratio of weights of two sphere of different materials is 8:17 and the ratio of weights per 1 cc of materials of each is 289 : 64. The ratio of radii of the two spheres is

A

`8:17`

B

`4:17`

C

`17:4`

D

`17:8`

Text Solution

Verified by Experts

The correct Answer is:
A
`(r_(1)/r_(2))=root(3)((8xx64)/(289xx17))=(8/17)^(3/3)=8/17`
`r_(1):r_(2)=8:17`
