Question

When equating the gravitational force with Newton's Second Law force to derive g, which term cancels out?

Options

• Mass of Earth (M)

• Mass of object (m)

• Radius of Earth (R)

• Gravitational constant (G)

Answer 1

Mass of object (m)

Explanation:

When equating GMm/r² = mg and solving for g, the mass of the object (m) cancels out from both sides, giving g = GM/r². This shows that g is independent of the object's mass.
