if the earth were to shrink suddenly,what will happen to the length of the day

If the earth were to shrink its speed would increase. This can be shown using conservation of angular momentum.
This is similar to the increase in speed of a dancer who initially has her hands stretched out and then draws them in.
If the earth rotates faster, the duration of a day decreases.
