Multiple choice

  1. The solar system was formed from the primitive sun and another intruding star
  2. The intruding star was smaller in size than the primitive sun
  3. The primitive sun was rotating on its axis.
  4. The tidal force of intruding star was greater than the primitive sun Which of the axioms given above were presented by Sir James Jeans?

  1. 1, 2 and 3

  2. 2, 3 and 4

  3. 1, 2 and 4

  4. 1, 3 and 4

D Correct answer
Explanation

Sir James Jeans and Chamberlin's Tidal Hypothesis (1919) proposed that a passing star exerted tidal force on the primitive sun, pulling out material that formed planets. The sun was rotating, and the intruding star's tidal force was greater than the sun's gravitational hold. Axiom 2 (star being smaller) is not part of Jeans' original formulation.
