Question

If I know the position of a sub
atomic particle precisely, then
Select one:
the particle must be at rest
i know a very limited amount
about particle's momentum
the particle cannot be at rest
i know nothing about the
particle's momentum​

Answer 1

Answer:

A

Explanation:

this the correct answer

Answer 2

Answer:

According to Heisenberg's uncertainty principle, it is impossible to know the position y and the momentum of  a sub atomic particle precisely.

Concept:

• Momentum: It is a ratio of the mass of a particle to the velocity. Momentum is a vector quantity; which means it has both magnitude and direction.
• Sub atomic particle: They are fundamental particles of the matter also  known as elementary particle.
• Dual nature of light: A light is having both particle and wave nature . When it is in motion considered as a wave and as a particle at the time of interaction with matter.
• Position: It is a place where particle is located in a space.

Heisenberg's uncertainty principle:

It states that,

• It is impossible to calculate the position and momentum of a matter at the same time with absolute accuracy.

Δx·Δp ≥ h/ 4π

Where,

x = position

p = momentum = mΔv

h= Plank's constant

m= mass

v= velocity

• It arises from the duel wave-particle nature. Every particle is associated with  wave .The particle is most likely to be found in those places where the dual nature of wave does not exist.
