Question

Which of the following confirms that gravitational mass and inertial mass are equal?

1.Free-fall accleration is the same throughout the universe
2.Free fall acceleration is the same at all points where the gravitational field stength is the same
3.Newton's second llaw is valid throughout the universe
4.An objects's weight can change with location but the object's mass remains constant.


Thank you for any help-I'm really confused on this question.
