Question

The electrons cannot exist inside the nucleus because:
  1. De-Broglie wavelength associated with electron decay is much less than the size of the nucleus.
  2. De-Broglie wavelength associated with electron decay is much greater than the size of the nucleus.
  3. De-Broglie wavelength associated with electron decay is equal to the size of the nucleus.
  4. negative charge cannot exist in the nucleus.

A
De-Broglie wavelength associated with electron decay is equal to the size of the nucleus.
B
De-Broglie wavelength associated with electron decay is much greater than the size of the nucleus.
C
De-Broglie wavelength associated with electron decay is much less than the size of the nucleus.
D
negative charge cannot exist in the nucleus.
Solution
Verified by Toppr

The de-Broglie wavelength of electron decay is several times greater than the size of nucleus. As a result an electron cannot be confined inside the nucleus. Thus answer for the question is option B.
