Question

the uncertainty in the measurement of position is (1/π) meter then uncertainty in the measurement of momentum cannot be (h is plank's constant) :
A) h/8 / meter
B) h/4 /meter
C) h/2 / meter
D h/16 /meter​

Answer 1

Answer:

b

Explanation:

Correct option is

B

2m

1

π

h

If uncertainty in the measurement of position and momentum are equal then uncertainly in the measurement of velocity is equal to

2m

1

π

h

.

ΔxΔP=

4π

h

But Δx=ΔP

Hence, Δx=ΔP=

4π

h

But ΔP=mΔu

Hence,

Δu=

2m

1

π

h
