Uncertainty in position of a 0.25g particle is

{10^{ - 5}}m.

The uncertainty in its velocity will be

View answer and explanation

Correct option: B

2.1 \times {10^{ - 26}}

Option B (

2.1 \times {10^{ - 26}}

) is correct because it is the uncertainty in velocity calculated using the Heisenberg Uncertainty Principle.
