A golf ball of mass '\(m\)' has a speed of \(50 \mathrm{~ms}^{-1}\), If the speed can be measured within accuracy of \(2 \%\), the uncertainty in the position is
- A \(\frac{h}{4 \pi m}\)
- B \(\frac{h}{16 \pi m}\)
- C \(\frac{h}{4 \pi m} \times 10^3\)
- D \(\frac{h}{16 \pi m} \times 10^3\)
Answer & Solution
Correct Answer
(C) \(\frac{h}{4 \pi m} \times 10^3\)
Step-by-step Solution
Detailed explanation
The uncertainty in the speed is \(2 \%\) i.e. \(50 \times \frac{2}{100}=1 \mathrm{~ms}^{-1}\) According to Heisenberg uncertainty principle,…
