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 rests on the sphere. The string makes an angle `alpha = 30^(@)` with the vertical. Find the acceleration of the sphere immediately after it is released. There is no friction anywhere.

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) :

A bob of mass m=50g is suspended form the ceiling of a trolley by a light inextensible string. If the trolley accelerates horizontally, the string makes an angle thata=37^(@) with the vertical. Find the acceleration of the trolley.

A bob of mass m=50g is suspended form the ceiling of a trolley by a light inextensible string. If the trolley accelerates horizontally, the string makes an angle 37^(@) with the vertical. Find the acceleration of the trolley.

One end of a light string is fixed to the celling and the other end is tied to the wall. A body of mass 500 g is suspended from that string in such a way that the part of the string towards the wall remains horizontal and the portion towards the ceiling makes an angle of 30^(@) with the ceiling. Find the tension on the two parts of the string.

A sphere of mass 20 g is whirled around in a horizontal circular path on the end of a string, the other end of which is stationary. If the tension in the string is 12.62 N, calculate the length of the string.

A block of mass m_(1) rests on a horizontal table. A string tied to the block is passed on a frictionless pulley fixed at the end of the table and to the other end of string is hung another block of mass m_(2) . The acceleration of the system is
