A conical pendulum has string length 5 m and its bob moves in a horizontal circle of radius 3 m. Take g=10 m/s². If ω²=N/2, find N.

The vertical height from the point of suspension to the plane of the circular path is h = √(l²−r²) = √(5²−3²) = √16 = 4 m. For a conical pendulum, ω² = g/h = 10/4 = 5/2 rad²/s². Hence N=5.
