When you experience a downward gravitational force from earth, earth likewise experiences an upward gravitational force from you. the second force will be substantially weaker. when you experience a downward gravitational force from earth, earth likewise experiences an upward gravitational force from you. the second force will be substantially weaker.

a. true
b. false

B) False

Explanation:

According to Newton’s third law of motion:

“Action and reaction forces are equal but opposite in direction”  

So, the force magnitude will be equal in both cases. The only difference will be in the magnitudes of masses and accelerations. The force experience by you has greater acceleration but less mass. On the other hand, force experienced by earth has greater mass (Mass of earth) and less acceleration. But in both cases, product of mass and acceleration remains constant. Hence, forces magnitudes will be equal and direction will be opposite.
