Question

A consequence of the equality of gravitational and inertial mass is that:
Options
A Heavier objects fall faster than lighter ones.
B All objects near the Earth fall with the same acceleration if air resistance is negligible.
Correct Answer
C Mass is not a property of an object.
D Gravity does not exist in a vacuum.
Correct Answer

Option B is the correct answer.

Detailed Explanation

If m_G (gravitational) equals m (inertial), then the acceleration a = F/m = (m_G g)/m = g. Since g is constant, all objects experience the same acceleration, regardless of their mass.

Hint

Think of Galileo's legendary experiment dropping objects from the Leaning Tower of Pisa.
