Question:
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.

The Correct Option is A
Solution and Explanation
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.

Concepts Used:
System of Particles and Rotational Motion
- The system of particles refers to the extended body which is considered a rigid body most of the time for simple or easy understanding. A rigid body is a body with a perfectly definite and unchangeable shape.
- The distance between the pair of particles in such a body does not replace or alter. Rotational motion can be described as the motion of a rigid body originates in such a manner that all of its particles move in a circle about an axis with a common angular velocity.
- The few common examples of rotational motion are the motion of the blade of a windmill and periodic motion.
