Question

proove that g=Gm/R2​

Answer 1

Step-by-step explanation:

we know that

F=GMm/R^2.......(1)

and by Newton's 2nd law....

F=Mg..........(2)

by eq(1)&(2)....

Mg=GMm/R^2

g=Gm/R^2

Answer 2

in this M=mass of earth and m=mass of the object.and r^2 =distence between the centre of the to the object because gravity is a centre force.
