G=GM/R(squared)? - gm g
What would be affected by the gravitational field at the surface of the earth when the earth was to be reduced in size without any change in mass? What is their relative strength to the surface if the earth had been halved in size? Size for a ticket?

g = GM / R () square?
ReplyDeleteR are reduced to R / 2, g '= GM / (R / 2) ^ 2 = 4 g
If it is reduced by R/10 RG = GM / (R/10) ^ 2 = 100 g
