A sphere of mass `M` is held at rest on a horizontal floor. One end of a light string is fixed at a point that is vertically above the centre of the sphere. The other end of the string is connected to a small particle of mass `m` that rest one the sphere. The string makes an angle `alpha = 30^(@)` with the vertical. Then the acceleration of the spherer immediately after it is released is : (There is no frication anywhere and string is tangene to the sphere) :
