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.)

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 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.)
Answer» SOLUTION :`V_e prop sqrt(M/R)` `V_(E1)/V_(E2)=sqrt(((6.0xx10^24)/(7.4xx10^22))(1740/6400))=4.695/1`
