Find the ratio of escape velocities from the earth and the moon. (Mass of the earth =6.0 xx10^(24)kg , Radius of the earth = 6400km, Mass of the moon = 7.4xx10^(22)kg Radius of the moon = 1740km.)

Find the ratio of escape velocities from the earth and the moon. (Mass

1.	Find the ratio of escape velocities from the earth and the moon. (Mass of the earth =6.0 xx10^(24)kg , Radius of the earth = 6400km, Mass of the moon = 7.4xx10^(22)kg Radius of the moon = 1740km.)
Answer» SOLUTION :Hint: `V_(e) prop sqrt(M/R)` `V_(E1)/V_(E2)=sqrt(((6.0xx10^(24))/(7.4xx10^(22)))((1740)/(6400)))=(4.695)/1`
