Multiple Choice Options

  • A 2:03
  • B 2:01
  • C 5:6\sqrt{5}:\sqrt{6}
  • D 1:21:\sqrt{2}

Step-by-Step Verified Solution

Radius of gyration of disc about a tangential axis in the plane of disc is 5 2 R = K 1 , radius of gyration of circular ring of same radius about a tangential axis in the plane of circular ring is K 2 = 3 2 R _ K 1 K 2 = 5 6
