The figure shows a schematic of a simple Watt governor mechanism with the spindle O1O2 rotating at an angular velocity ω about a vertical axis. The balls at P and S have equal mass. Assume that there is no friction anywhere and all other components are massless and rigid. The vertical distance between the horizontal plane of rotation of the balls and the pivot O1 is denoted by h. The value of h = 400 mm at a certain ω. If ω is doubled, the value of h will be _________ mm.
  • a)
    50
  • b)
    100
  • c)
    150
  • d)
    200
Correct answer is option 'B'. Can you explain this answer?
Most Upvoted Answer
The figure shows a schematic of a simple Watt governor mechanism with ...
ω2 = g / h or watt governor
(ω ∝ N)
N2 = g / h 

h1 = 400 Given

ω2 = 2ω1

h2 = 100
Hence, the correct option is (B).
