A particle travels around a circle of radius equal to 4 m, changing its speed at a constant rate. At a certain point A, the speed is recorded to be 3 m/s, after travelling another quarter revolution to point B, the speed has increased to 6 m/s. Determine the magnitude of the acceleration of the particle at B.
