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

(A) $\dfrac{v^{2}}{R}\widehat{l}+\dfrac{v^{2}}{R}\widehat{j}$

(B) $-\dfrac{v^{2}}{R}\cos \theta \widehat{l}+\dfrac{v^{2}}{R}\sin \theta \widehat{j}$

(C) $-\dfrac{v^{2}}{R}\sin \theta \widehat{l}+\dfrac{v^{2}}{R}\cos \theta \widehat{j}$

(D) $-\dfrac{v^{2}}{R}\cos \theta \widehat{l}-\dfrac{v^{2}}{R}\sin \theta \widehat{j}$

Solution:
