For a particle in uniform circular motion,the acceleration $\vec{a}$ at a point $P(R, \theta)$ on the circle of radius $R$ is (Here $\theta$ is measured from the $x$-axis):

• A
  $\frac{V^2}{R}\hat{i} + \frac{V^2}{R}\hat{j}$
• B
  $-\frac{V^2}{R}\cos\theta\hat{i} + \frac{V^2}{R}\sin\theta\hat{j}$
• C
  $-\frac{V^2}{R}\sin\theta\hat{i} + \frac{V^2}{R}\cos\theta\hat{j}$
• D
  $-\frac{V^2}{R}\cos\theta\hat{i} - \frac{V^2}{R}\sin\theta\hat{j}$
