A solid sphere with uniform density and radius 
is rotating initially with constant
angular velocity 
about its diameter. After some time during the rotation its starts loosing mass at a uniform rate, with no change in its shape. The angular velocity of the sphere when its radius become 
is 
. The value of 
is 
.

(32)
When sphere is of radius R , its mass is M , when radius is reduced to 
, mass will reduced to 
Now by conservation of angular momentum
value of x is 32
