If $\Delta x$ is the uncertainty in position and $\Delta v$ is the uncertainty in velocity of a particle are equal,the correct expression for uncertainty in momentum for the same particle is

  • A
    $\frac{1}{4} \sqrt{\frac{m h}{\pi}}$
  • B
    $\frac{1}{3} \sqrt{\frac{m h}{2 \pi}}$
  • C
    $\frac{1}{2} \sqrt{\frac{m h}{\pi}}$
  • D
    $\frac{1}{2} \sqrt{\frac{h}{m \pi}}$
