Question
Physics Question on System of Particles & Rotational Motion
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. As the mass of opponent is brought closer to the fighter?s hip, the force required to throw the opponent is reduced.
If both assertion and reason are true and reason is the correct explanation of assertion
If both assertion and reason are true but reason is not the correct explanation of assertion
If assertion is true but reason is false
If both assertion and reason are false
If both assertion and reason are true and reason is the correct explanation of assertion
Solution
The judo fighter in order to throw his opponent on the mat tries to initially bend his opponent and then rotate him around his hip because by doing this the weight of opponent is made to pass through the hip of judo fighter to make its torque zero.
