For a particle in uniform circular motion, the acceleration a at any point P(R, θ) on the circular path of radius R is (when θ is measured from the positive x-axis and v is uniform speed):

(C) - (v²)/R cos θ i - (v²)/R sin θ j

(A) - (v²)/R sin θ i + (v²)/R cos θ j

(B) - (v²)/R cos θ i + (v²)/R sin θ j
