Which statement is a correct consequence of the uncertainly principle?
A
A particle’s kinetic energy cannot be measured accurately at any time
B
Both momemtum and energy of a particle can be known with absolute certainly
C
It is possible to measure exactly both the position and momentum of a particle at the same time
D
The complete knowledge of the position of a particle implies the complete ignorance of its energy
E
The uncertainty in our knowledge of energy and the duration taken to measure it, are each less than Planck’s constant.
Verified Correct Answer: D.
Physical Principles & Numerical Solution
This statement effectively captures the essence of the uncertainty principle, which states that if you have precise information about one property (such as position), it restricts your ability to know another property (like momentum and energy) accurately.
