A solid sphere of radius `r` and mass `m` is spining about a diameter as axis with a speed `omega_(0)`. The temperature of the sphere increases by `100^(0)C` without any other disturbance. If the coefficient of linear expansion of material of sphere is `2 xx 10^(-4 //0) C`, the ratio of angular speed at `100^(0)C` and `omega_(0)` is
