1 N.

The equal, but opposite answer is correct. But you can also see this through:

F = G(Mm)/r^2, which states that the gravity force between two point masses (M and m) is F at r distance between them. G is a constant. The "force" in your assumption is 1 N; so that 1 N (the weight) is equally valid when talking about the Earth (M) acting on the apple (m) or vice versa.
