Rotational MotionHard
Question
Find minimum height of obstacle so that the sphere can stay in equilibrium
Options
A.
B.
C.R (1 - sin θ)
D.R (1 - cos θ)
Solution
Sphere is on verge of toppling when line of action of weight passes through edge.
cos θ =
⇒ h = R - R cos θ
cos θ =
⇒ h = R - R cos θ Create a free account to view solution
