Assertion : The earth is slowing down and as a result the moon is coming nearer to it. Reason : The angular momentum of the earth moon system is not conserved.

Options

  1. Aif both assertion and reason are true and the reason is the correct explanation of the assertion
  2. Bif both assertion and reason are true and the reason is not the correct explanation of the assertion
  3. Cif assertion is true but reason is false
  4. Dif both assertion and reason are false statements.

Correct answer

D. if both assertion and reason are false statements.

Step-by-step solution

One of the basic requirement of the existence of all planetary motions is the conservation of angular momentum. If this law is violated, then no gravitational law will be able to explain the behaviour of the planets and the satellites as they do.
