The point A moves with a uniform speed along the circumference of a circle of radius $\displaystyle 0.36$ m and covers $\displaystyle 30$° in $\displaystyle 0.1$ s. The perpendicular projection 'P' from 'A' on the diameter MN represents the simple harmonic motion of 'P'. The restoration force per unit mass when P touches M will be :
