A scale.

A simple scale. The weight of an object IS the force of gravity on it.

You don't need one.
All you need is the mass of the objects in question (the small object you're talking about, and whatever it is that's exerting gravity on it) and the distance between each object's center point.
F = (GMm)/R²
Where G is the universal gravitational constant, 6.67*10-11 N-m²/kg², M is the mass of the big body, and m is the mass of the little body.
EDIT:
Or, if this is a trick question, a scale. Dangit.
