Heisenberg's uncertainty principle

In Heisenberg's uncertainty principle the uncertainty of ----& ----is discussed

• Position & mass

• Positon and temperature

• Postion and velocity

• Position and energy

What is momentum?

• the speed of a particle

• mass times velocity

• the total movement in a system

• mass divided by velocity

Consequence of Heisenberg's uncertainty principle is ---------

• Rules out the 2dimensional path around the nucleus for the electrons

• Predict the existence of region around nucleus for the electrons

• Establishes the wave character for the electrons

• All the above statements

If uncertainty in position of an electron is zero, the uncertainty in its momentum will be

• < h/4ℼ

• >h/4ℼ

• 0

• ∞

Calculate the uncertainty in the position of particle if the uncertainty in momentum is 1x10^-3gcm/s

• 0.527x10^-24cm

• 0.302x10^-24cm

• 1.325x10^-23cm

• 1.206x10^-23cm
