A particle is attached to one end of a light inextensible string. The other end of the string is attached to a fixed point O. The particle is set into motion, so that it describes a horizontal circle whose centre is vertically below O. The angle between the string and the vertical is theta, as shown in the diagram.

(a) The particle completes 40 revolutions every minute. Show that the angular speed of the particle is 4.19 radians per second, to three significant figures.

(b) The radius of the circle is 0.2 metres. Find the magnitude of the acceleration of the particle.

(i) Draw a diagram showing the forces acting on the particle.

(ii) Explain why T cosθ = mg.

(iii) Find the value of θ, giving your answer to the nearest degree.
