th​

Answer 1

Answer:

F=GMm/r²

mass of earth be M

mass of object be m

distance between earth surface and object be r

Therefore F=GMm/r²

Hope this answer helps you

Answer 2

Answer:

let mass :M

let the mass of object be:m

distance between the earth centre and object:Radius =R

Gravitational force;F: GM/R2
