Question

4) r" 03. the escape speed of a body from the surface of earth (radius of earth = r,) is​

good afternoon guys ☺️

Answer 1

the escape velocity from the surface of the earth is

ve= 2GM/RE...(1) acceleration due to gravity

G= REE2/GM

RE. GG=gR F..(2)

substitude equation(2) in equation (1),

ve=√2 gRE,,
