Assertion : The length of the day is slowly increasing. Reason : The dominant effect causing a slowdown in the rotation of the earth is the gravitational pull of other planets in the solar system.

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

C. if assertion is true but reason is false

Step-by-step solution

Because of the gravitational pull of other planets in the solar system, the earth cannot get slowed down in rotation. Because, if it happens so, it will affect the conservation of angular momentum which is not possible.
