Question

Q.1 Calculate the uncertanity in the position of a particle when the uncertanity in

momentum is a) 1 x 10-3

gcm sec-1

b) Zero (h = 6.62X 10-34 Js)

​

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.
