18M.2.HL.TZ2.1d.i
The ball is now displaced through a small distance x from the bottom of the bowl and is then released from rest.
The magnitude of the force on the ball towards the equilibrium position is given by
where R is the radius of the bowl.
(d.i)
Outline why the ball will perform simple harmonic oscillations about the equilibrium position.
