Question & Answer
Choose the Best Answer
You can measure both precisely without limitations.
Increased precision in measuring one leads to increased uncertainty in the other.
The principle only applies to large macroscopic objects.
Energy and momentum can be measured accurately in a stable system.
Understanding the Answer
Let's break down why this is correct
The principle says that a particle’s energy and momentum are linked. Other options are incorrect because Option A suggests we can know both exactly; Option C claims the rule only applies to big things.
