Question

"the velocity of an electron and its exact position cannot be determined at a time".Do you agree with this statement?-Explain​

Answer 1

Yes, the statement is true

• Heisenberg uncertainty principle states that the position and velocity of the object cannot be measured excatly at the same time

• This arises due to the fact that the electrons will not have definite position and the direction of the motion at the same time

• The  concept of exact position and exact velocity together have no meaning in nature
• So the statement "the velocity of an electron and its exact position can’t determined at a time" is true
