Answer:

The cloud will spin faster.

Explanation:

According to law of conservation of angular momentum, when the mass size is same, if the size of the collapsing cloud decrease, its it angular velocity should increase.

Angular momentum L =mrω^2

Since L and m is constant , to keep L same. when r is decreased ω must increase. Therefore, the cloud will spin faster.
