Which of the following is true?
  • a)
    Each decay product has the same speed
  • b)
    The Thorium nucleus has more momentum than the Helium nucleus
  • c)
    Each decay product has the same kinetic energy 
  • d)
    The Helium nucleus has more kinetic energy than the Thorium nucleus.
Correct answer is option 'D'. Can you explain this answer?
Verified Answer
A Uranium nucleus decays at rest into a Thorium nucleus, as shown.Whic...
Since the U nucleus decays at rest.
∴  The products have equal and opposite value of momenta.
The product with greater mass will have lower K.E.

The correct answer is: The Helium nucleus has more kinetic energy than the Thorium nucleus.
