For a particle in uniform circular motion, the acceleration a at a point P(R,θ) on the circle

Question

For a particle in uniform circular motion, the acceleration vector a at a point P(R,θ)  on the circle of R is (Here θ is  measured from the x-axis)

(a) v²/R i+v²/R j

(b) -v²/R cosθ i+ v²/R sinθ j

(c)  -v²/R sinθ i+ v²/R cosθ j

(d)  -v²/R cosθ i+ v²/R sinθ j

Answer 1

Correct Option  (d)  -v²/R cosθ i+ v²/R sinθ j
