It will be stable only if;
LHS MOMENTS = RHS MOMENTS
i,e
2w * x * x/2 = w * y * y/2.
y = (2)^1/2 * x.
LHS MOMENTS = RHS MOMENTS
i,e
2w * x * x/2 = w * y * y/2.
y = (2)^1/2 * x.

@Krishna.
Rest 3 cases for unstable.

Then what for unstable?

For stable condition.
w*y*y/2=2w*x*x/2.
y^2=2*x^2.
y=√2*x.
w*y*y/2=2w*x*x/2.
y^2=2*x^2.
y=√2*x.

It should be 2x=y.

Well said @Henal.

For stable condition:
2W*X*X/2 = W*y*y/2.
Therefor, y = 2^1/2*x.
2W*X*X/2 = W*y*y/2.
Therefor, y = 2^1/2*x.
