Question

The uncertainty in the position and velocity of the particle are 10^-12m and 5.27 x10^-5 A^0 respectively. Calculate mass of the particle.​

Answer 1

ANSWER

According to Heisenberg's uncertainty principle,

Δx⋅mΔv=

4π

h

or m=

4πΔx⋅Δv

h

=

4×3.143×10

−10

×5.27×10

−24

6.625×10

−34

=0.099kg.
