Part 1 of 2 A particle travels clockwise on a circular path of diameter R, monitored by a sensor on the circle at point P; the other endpoint of the diameter on which the sensor lies is Q. Let @ be the angle between the diameter PQ and the line from the sensor to the particle. Let c be the length of the chord from the particle's position to Q. Complete parts a and b below.
