A small sphere of mass m is connected by a string to a nail at O and moves in a circle of radius r on the smooth plane inclined at an angle with the horizontal If the sphere has a velocity u at the top position A Mark the correct options B C 90 U O A 0 37 Minimum velocity at A so that the string does not get slack instantaneously is 3 5gr Tension at B is 9mg 5 if the sphere has the required velocity as in option A
