TheMigthyBat, no they're attached as in bolted together. You don't know the weight of either of them. And it's not about finding the heavier of them, it's about finding the exact weight of one of them without disturbing them.

Cant we just see the amount of water displaced by the object and then calculate the weight?

I think its easy that way, as we can control the volume immersed in water. (let it be attached in any way)

I think we can take a perfect model of both objects and weigh them separately...

by immersing them in a liquid....one by one....and checking the amount of volume displaced.......and applying principles on the liquid collected

immersing in the liquiud is the ans to thi s ques ... bt still then they are connected together so the total volume obtained would the sum of both objects .. then how could we find the volume of each one ..

Water displacement theory seems to be nice. Since there is no information regarding how they are attached we can do the following way.

catch one weighted and dip the other weight in water. Some water will be displaced. Now repaeat the same in revesrese order. i.e catch the second side and dip the other weight. Now calculate the amount of water displaced in both the cases. greater displacement - lesser water displacement. Now immerse completely both the objects and find the displacement of water. by this you can arrive at the answer

its simply and easy. Let us use the simple way to determine which is heavier. Let us assume the weights are connected with the thread.

And use the water displacement. And we can use the six standard mathematics (A+b) whole square formulae. We can calculate the weight of the object

If the objects are linked by a thread, I'd just put each object one side of my arm and let the heavier one go down while the lighter one goes up
