(A) : The hard boiled egg and raw egg can be distinguished on the basis of spinning of both.

(R) : The moment of inertia of hard boiled egg is more as compare to raw egg.

While a raw egg contains liquid, a hardboiled egg behaves like a rigid body. 

Due to centrifugal force, when rotated, the liquid is pushed out from the centre. 

Since raw eggs have more moment of inertia than boiled eggs do, they spin with less angular acceleration because their mass is dispersed farther from the axis in raw eggs than it is in boiled eggs. 

So, boiling eggs will spin more quickly than raw ones.

Hence the correct answer is ‘A’ is true and ‘R’ is false.
