Answer 1

[1]

The Universal Gravitational constant G has the unit = m/s²

===========================

[2]

=> F = mg

=> F = 1×9.8 = 9.8 N

==========================

[3]

» the value of g :- is constant on the surface of the Earth

==========================

[4]

=> Fb=Fe
(since Newton's third law says every action has an equal and opposite reaction)

Note that we cannot see the movement of earth towards the ball because the force exerted by the ball is much less for the earth to be moved but the force exerted by earth is
enough to move the ball
