Dear pallavi

 stone makes 22 revolutions in 44 seconds

 or 1/2 revolution in 1 sec

so angular velocity ω = ∏ rad /sec

only centripital acceleraion is acting = ω2 L

                                                                    =∏2 * 1

                                                                    =9.869 N

direction is towards the center of circle
