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 the opponent is brought closer to the fighter's hip, the force required to throw the opponent is reduced.
Options
- AIf both assertion and reason are true and reason is the correct explanation of the assertion
- BIf both assertion and reason are true but reason is not the correct explanation of the assertion
- CIf assertion is true, but reason is false
- DBoth assertion and reason are false statements.
Correct answer
A. If both assertion and reason are true and reason is the correct explanation of the assertion
Step-by-step solution
Rotation of the opponent makes it difficult for the person rotated to resist. Any torque given by a force by pushing the person about an axis will be resisted but not the torque by rotation. By bringing him close to the hip, the opponents moment of inertia is reduced.
