Answer 1

Answer:√(2/5)r

Explanation:

Radius of gyration of a uniform solid sphere about its diameter is √(2/5)r.

Radius of gyration is the distance from the axis of rotation to the point where we suppose the whole mass is concentrated.

Hence, radius of gyration of a uniform solid sphere about its diameter is √(2/5)r.
