Find the ratio of escape velocities from...

Find the ratio of escape velocities from the earth and the moon. (Mass of the earth = `6.0 xx 10^24` kg, Radius of the earth = 6400km, Mass of the moon = `7.4 xx 10^22` kg Radius of the moon 1740 km.)

Text Solution

Verified by Experts

`V_e prop sqrt(M/R)`
`V_(e1)/V_(e2)=sqrt(((6.0xx10^24)/(7.4xx10^22))(1740/6400))=4.695/1`
