Question

find the radius of gyration of a solid sphere of radius 5 centimetre 1)about the tangent 2)about the diameter ​

Answer 1

Answer:

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.
