The displacement of a particle moving over three quarters of a circle is calculated by finding the straight line distance between the starting point and the ending point of the movement.

Step 1: Identify the starting and ending points. In a circle, if a particle moves three quarters, it ends up at the diametrically opposite point from where it started.

Step 2: The displacement is the diameter of the circle in this case, because the diameter is the straight line distance between two points on a circle that passes through the center.

Step 3: The diameter of a circle is twice the radius. So, if the radius is r, the diameter (and thus the displacement) is 2r.

So, the magnitude of the displacement of the particle is 2r.
