What will be acceleration due to gravity on the surface of the moon if its radius were `(1//4)^(th)` the radius of earth and its mass `(1//80)^(th)` the mass of earth? What will be the escape velocity on the surface of moon if it is `11.2 km//s` on the surface of the earth? (given that `g=9.8 m//s^(2)`)

Answer

`[196cm//s^(2)]`
