Questions
The radius of gyration of a body about an axis at a distance 6 cm from its centre of mass is 10 cm. Then its radius of gyration about a parallel axis through its centre of mass will be
detailed solution
Correct option is B
According to theorem of parallel axesI=ICM+Ma2 or ICM=MK2−Ma2=MK2−a2=M(100−36)=M×64=M×(8)2∴ K=8cmTalk to our academic expert!
