Answer:
decreases
Explanation:
The angular frequency of the mass is given by
[tex]\omega =\sqrt{\frac{k}{m}}[/tex]
where, k is the spring constant and m be the mass of the body which is doing oscillations.
if the mass of the body increases, so the value of angular frequency decreases, as the angular frequency is inversely proportional to the square root of the mass of the body.
