A Marble Is Dropped Straight Down from a Distance H

Multiple Choice

A marble is dropped straight down from a distance h above the floor. Let F_m = the magnitude of the gravitational force on the marble due to the earth;
F_e = the magnitude of the gravitational force on the earth due to the marble;
A_m = the magnitude of the acceleration of the marble toward the earth;
A_e = the magnitude of the acceleration of the earth toward the marble.
Which set of conditions is true as the marble falls toward the earth? Neglect any effects of air resistance.

A) F_m = F_e and a_m < a_e
B) F_m < F_e and a_m > a_e
C) F_m < F_e and a_m = a_e
D) F_m > F_e and a_m = a_e
E) F_m = F_e and a_m > a_e
