Which of the following statements is $correct$?

  • A
    An electron cannot exist inside the nucleus because the uncertainty in speed becomes greater than the speed of light.
  • B
    The wavelength associated with a $1 \ g$ particle moving with a velocity of $100 \ m/s$ has physical significance.
  • C
    It is possible to determine the position as well as momentum precisely for a very fast-moving particle.
  • D
    An electron having a total kinetic energy of $E_1$ has a wavelength associated with it equal to $\frac{hc}{E_1}$ [$h =$ Planck's constant].
