The escape velocity of a sphere of mass ...

The escape velocity of a sphere of mass m is given by (G= univesal gravitational constant, `M_(e) =` mass of the earth and `R_(e) =` radius of the earth)

`sqrt(frac(2GM_e m )(R_e) `

`sqrt(frac(2GM_e )(R_e)`

`sqrt(frac(GM_e )(R_e) `

`sqrt(frac(2GM_e -R_e )(R_e) `
