Assertion : A judo fighter in order to throw his opponent on to the mat tries to initially bend his opponent and then rotate him around his hip. Reason : As the mass of opponent is brought closer to the fighter's hip, the force required to throw the opponent is reduced.

Options

  1. AIf both assertion and reason are true and reason is the correct explanation of assertion.
  2. BIfboth assertion and reason are true but reason is not the correct explanation of assertion.
  3. CIf assertion is true but reason is false.
  4. DIf both assertion and reason are false.

Correct answer

A. If both assertion and reason are true and reason is the correct explanation of assertion.

Step-by-step solution

Torque on the opponent by a judo fighter τ⃗=r⃗×F⃗=rFsin⁡θn^\vec{\tau}=\vec{r} \times \vec{F}=r F \sin \theta \hat{n}
