'It is just basic Physics,' or is that mechanics
RTQ,
But what
is the question; if taken from an EASA examination then what wording might constrain situational thoughts, and if so, to what purpose.
Knowing the relationship between yaw and CG appears to have little practical value.
However, in actual conditions the need to control the aircraft with rudder, which could be influenced by CG, then crews should have this knowledge - and of many other operational factors depending on the situation. e.g. stick fwd, crosswind, runway width / surface condition.
