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 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

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 mass of 5 kg tied to a string of length 1.0 m is rotated in vertical circle with a uniform speed of 4 m//s . The tension in the string will be 170 N when the mass is at (g = 10 m//s^2)

Choose the correct options A uniform rod of mass 2 m is held horizontal by two sturdy, practically inextensible vertical strings tied at its ends. A boy of mass 3 m hangs himself at one third length of the rod. Ratio of the tension in the string close to the boy to that in the other string is

Three blocks with masses m, 2m and 3m, are connected by strings, as shown in the figure. After an upward fforce F is applied on block m, the masses move upward at constant speed v. What is the net force on the block of mass 2m? (g is the acceleration due to gravity)

A body of mass 0.1 kg tied to a string of length 5 m is revolved in a vertical circle such that the maximum tension in the string is 9N. The minimum tension in the string is A. 0N B. 3N C. 4N D. 6N

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
