According to Newton's 3rd law, the force on the (smaller) moon due to the (larger) earth is

Question

greater in magnitude and antiparallel to the force on the earth due to the moon.

greater in magnitude and parallel to the force on the earth due to the moon.

equal in magnitude but antiparallel to the force on the earth due to the moon.

equal in magnitude and parallel to the force on the earth due to the moon.

smaller in magnitude and antiparallel to the force on the earth due to the moon.

smaller in magnitude and parallel to the force on the earth due to the moon.

Answer 1

greater in magnitude and parallel to the force on the earth due to the moon.

Answer 2

Greater & parallel.

Answer 3

Newton's 3rd law basically says that for every action there is an EQUAL and opposite reaction.

The reason that the moon orbits the earth, is that its mass is lower.

Newton's 2nd law: F = ma

says that for a given force, a smaller mass will accelerate more than a bigger mass.

So even tho the force of gravity exerted by the moon on the earth is the same as the force the earth exerts on the moon, the moons lower mass means it is more affected by the force.

Same goes for the force between the sun and the earth and why the earth orbits the sun.

ADDED: what's with the thumbs down. what I said is true and give all the information necessary to answer what is obviously a homework question...
