The radius of a planet is R . A satellite revolves around it in a circle of radius r with angular speed .The acceleration due to gravity on planet’s surface will be :

• A

  $\frac{r^3\omega }{R}$

• B

  $\frac{r^2{\omega }^3}{R}$

• C

  $\frac{r^3{\omega }^2}{R^2}$

• D

  $\frac{r^2{\omega }^2}{R}$
