From study of elastic collision we understand that if two colliding particles have equal masses they interchange their velocities and energy transfer is maximum if they have equal masses and one is at rest w... other. This principle can be easily used in nuclear reactor to select a moderator. If `m_(1)=m_(2)=m` and `m_(2)` at rest then `m_(1)` will stop after colliding with `m_(2)` and `m_(2)` will move with velocity of `m_(1)`. In case of nuclear reactor we used a moderator such that neutrons can be slowed down. With above reference answer the following questions
Which is correct statement

A

Soft water can be used as moderator

B

Heavy water is used as moderator

C

Hard water is used as moderator

Hard water or Heavy water can be used as moderator
