Governor is stable, when the:a)Radius of rotation of balls increases a...
A governor is said to be stable when for every speed within the working range there is a definite configuration i.e. there is only one radius of rotation of the governor balls at which the governor is in equilibrium. For a stable governor, if the equilibrium speed increases, the radius of governor balls must also increase. A governor is said to be unstable, if the radius of rotation decreases as the speed increases.

Explanation:
Governor is a device that is used to control the speed of an engine. It consists of two balls that are attached to a central spindle. As the speed of the engine increases, the centrifugal force acting on the balls increases, causing them to move outward. This movement of the balls is used to control the fuel supply to the engine, which in turn controls its speed.
Stable Governor:
A governor is said to be stable when it is able to maintain a constant speed of the engine under varying load conditions. A stable governor operates at a fixed equilibrium speed, which is the speed at which the centrifugal force acting on the balls is equal to the force of gravity. The equilibrium speed of a governor depends on the radius of rotation of the balls.
Effect of Radius of Rotation of Balls on Equilibrium Speed:
The equilibrium speed of a governor is directly proportional to the radius of rotation of the balls. This means that as the radius of rotation of the balls increases, the equilibrium speed of the governor also increases. Similarly, as the radius of rotation of the balls decreases, the equilibrium speed of the governor also decreases.
Relation between Radius of Rotation of Balls and Equilibrium Speed:
From the above explanation, it is clear that option 'B' is the correct answer. The radius of rotation of balls increases as the equilibrium speed of the governor increases. This is because the centrifugal force acting on the balls increases with an increase in the radius of rotation. As a result, the equilibrium speed of the governor also increases.
Conclusion:
A stable governor is an essential component of an engine that helps to maintain a constant speed under varying load conditions. The equilibrium speed of a governor depends on the radius of rotation of the balls. A governor is said to be stable when it is able to maintain a constant speed of the engine under varying load conditions.
