Question

The mass of electron is 9.8×10^-28gram and uncertainty in the velocity equal to 2×10^-3cm/second. The uncertainty in position of electron is (planks constant=(6.62×10^-27erg second)

Answer 1

Explanation:

Using the formula: Δx×Δp=

4π

h

.

Now, Δp=mΔv=9.1×10

−28

gm×2×10

−3

cm/sec=1.82×10

−30

gmcm/sec=1.82×10

−35

kgm/sec

Therefore, Δx=

4πΔp

h

=2.9m=2.9×10

2
