A solid sphere of mass 500 g radius 5 cm is rotated about one of its diameter with angular speed of 10 rad s -1 . If the moment of inertia of the sphere about its tangent is x x 10 -2 times its angular momentum about the diameter. Then the value of x will be
Text Solution
Verified by ExpertsThe correct answer is:
35
(35)
The angular momentum about the diameter is
;
The moment of inertia of a sphere is I CM = 
MR 2 . The moment of inertia about the tangent is
It is given that 
= 10 rad s -l
Using the given relation between the moment of inertia and the angular momentum,
