Uncertainty in measuring the speed of a particle is numerically equal to the uncertainty in measuring its position. The value of these uncertainties will be

View answer and explanation

Correct option: D

Both (1) and (3)

Option D (Both (1) and (3)) is correct because the uncertainty principle states that the product of uncertainties in position and momentum must be greater than or equal to

\frac{h}{4 \pi}

, implying the uncertainty can be equal to or greater than

\sqrt{\frac{h}{4 \pi m}}

.
