For a particle in uniform circular motion the acceleration \overrightarrow{a} at a point P(R, \theta) on the circle of radius R is (here \theta is measured from the x-axis) [AIEEE 2010]

Correct Answer is : −v2Rcosθ∧i−v2Rsinθ∧j

-\frac{v^2}{R} \cos \theta \hat{i}+\frac{v^2}{R} \sin \theta \hat{j}

-\frac{v^2}{R} \sin \theta \hat{i}+\frac{v^2}{R} \cos \theta \hat{j}

-\frac{v^2}{R} \cos \theta \hat{i}-\frac{v^2}{R} \sin \theta \hat{j}

\frac{v^2}{R} \hat{i}+\frac{v^2}{R} \hat{j}
