When the relation between the controlling force (FC) and radius of rotation (r) for a spring controlled governor is FC = a.r + b, then the governor will be

When the relation between the controlling force (FC) and radius of rotation (r) for a spring controlled governor is FC = a.r + b, then the governor will be Correct Answer unstable

For the governor to be stable, the controlling force (FC) must increase as the radius of rotation (r) increases, i.e. FC / r must increase as r increases.
