Calculate te radus of an isolated sphere...

Calculate te radus of an isolated sphere of density `3.0 g cm^(-3)` from the surface of which the escape velocity be `40 ms^(-1)`

Text Solution

Verified by Experts

`v_(e)=sqrt((2GM)/R)=sqrt((2G(4/3pR^(3)rho))/R)`
`R=v_(e)sqrt(3/(8piGrho))=30894m=31km`
