Homework Statement

Given that a spring with a ball of mass m attached to it is oscillating in between x=A and x=-A where x=0 is the equilibrium position. Will the equilibrium position change when the the mass of the ball is doubled?

2. The attempt at a solution
I think that the equilibrium position will stay at zero and the amplitude will increases. Not sure though.

You are right, the equilibrium position does not change with mass if the spring is horizontal. But some characteristics of an SHM depends on the mass. What is it?
