Two masses of 20 kg and 10 kg are connected to the ends of a string, hanging on a smooth and frictionless pulley. Find the acceleration of the two masses and tension in the string.

Two bodies of masses 2 kg and 4 kg are connected at the two ends of a string of negligible mass that passes over an ideal pulley (i. e., of negligible mass and friction). Calculate (i) the acceleration of the system (ii) the tension in the string. [Given: g = 10 m//s^2 ]

A stone of mass 50 g is tied to the end of a string 2 m long and is set into rotation in a horizontal circle with a uniformspeed of 2 m//s . Then tension in the string is

A mass of 2 kg is whirled in a horizontal circle by means of a string at an initial speed of 5 revolutions per minute. Keeping the radius constant the tension in the string is doubled. The new speed is nearly

Three masses of 2 kg, 12 kg and 4 kg are connected to each other with threads and are placed on a table as shown in figure. If g=10" m s"^(-2) , the acceleration with which the system is moving is

A massless inextensible string with masses 1kg and 4kg attached to its two endsis passing over the pulley. Find the acceleration of the system using free body diagram.

Three masses m, 2m and 3m are attached with light string passing over a fixed frictionless pulley as shown in the figure. The tension in the string between 2m and 3m is (g is acceleration due to gravity)

Ten identical masses (m each) are connected one below the other wih 10 strings. Holding the topmost string, the system is accelerated upwards with acceleration g//2 . What is the tension in the 6th string from the top (topmost string being the first string)?

Two blocks of masses 10 kg and 4 kg are connected by a spring of negligible mass and placed on a frictionless horizontal surface. An impulse gives a velocity of 14 m//s to the heavier block in the direction of the lighter block. The velocity of the centre of mass is

A mass is supported on frictionless smooth horizontalsurface.It is attached to a string rotated about a fixed centre at an angular velocity to. If the length of the string and the angular velocity are doubled (the initial tension is T), then the tension in the string will be

A stone of mass1/2kg iswhirled round the end of a piece of string in a horizontal circle of radius half a meter with a uniform speed of 1 m//s . The tension in the string is
