Answer:
increases
Explanation:
The angular momentum of an object rotating about a point is given by:
where
m is the mass of the object
v is the velocity
r is the distance from the centre of the circular trajectory
In this problem, when you move towards the edge, the value of r (distance from the centre) increases. Assuming that the other quantities are not changing, this means then that the value of L, the angular momentum, is increasing.
