Whenever air resistance can be neglected or eliminated, an object in free fall near earth's surface accelerates vertically downward at 9.8m/s^s due to earths gravity. this acceleration is also called 1 g.

True

Explanation:

This statement regarding Free Fall is True.

In the case of Earth, when objects are dropped from a certain height and fall to the ground with the acceleration of the gravity , this is free fall.

In this sense, according to experiments done in vacuum (where there is not air or any fluid, hence there is not resistance), all objects in free fall experience the same acceleration, which is the acceleration due gravity that acts vertically downwards.  In addition, objects in free fall experience this acceleration regardless of their mass.

iron would move it is magnetic there is a mag field around the current in the wire

the answer is b, have negligible mass
