Right choice is (d) inversely proportional to (speed)^

To explain: If N is the speed of the arm and ball about the spindle axis, then the height of the governor (h) is given by

h = 895/N^2 metres

From this expression, we see that the height height of a Watt’s governor is inversely proportional to N^2
