Circular MotionHard
Question
A small block is placed inside a cylinder of radius R that rotates with angular speed ω about a horizontal axis as shown in figure. The maximum angle q reached by the block before it starts to slip is given by equation.
Options
A.g cos θ = μs(g sin θ + ω2R)
B.g sin θ = μs(g cot θ + ω2R)
C.g tan θ = μs(g cos θ + ω2R)
D.g sin θ = μs(g cos θ + ω2R)
Solution
N = mg cos θ + mω2R
& mg sin θ = μsN
