Which statement correctly identifies the type of mass that appears in each of the two fundamental equations F=ma and F=Gr2Mm?
a) F=ma contains the inertial mass, while F=Gr2Mm contains the gravitational mass.
b) Both equations contain only inertial mass.
c) Both equations contain both inertial and gravitational mass because the two kinds are equivalent in magnitude.
d) F=ma contains the gravitational mass, while F=Gr2Mm contains the inertial mass.
