A system to 10 balls each of mass 2 kg are connected via massless and unstretchable string . The system is allowed to slip over the edge of a smooth table as shown in figure . Tension on the string between the `7^(th) and 8^(th)` ball is _____ N when `6^(th)` ball just leaves the table .

Two blocks A and B , each of mass 10 kg , are connected by a light string passing over a smooth pulley as shown in the figure. Block A will remain at rest if the friction on it is

Two blocks of masses 10 kg and 20 kg are connected by a massless string and are placed on a smooth horizontal surface as shown in the figure. If a force F=600 N is applied to 10 kg block, then the tension in the string is

Two block of mass 5 kg and 10 kg respectively are connected by a massless string as shown in the figure. The whole system is kept on a frictionless surface. A force of 50 N is applied horizontally as shown in the figure. The tension T in the string will be

Two identical small balls, each of mass m , are connected by a massless and inextensible string of length l and placed on a smooth horizontal xy plane. An external agent pulling the string from its mid-point along y -axis with velocity v_(0) as shown in Fig. When the separation between the two balls reduces to l//2 then the speed of each ball will be

Two blocks A & B are connected by a light inextensible string passing over a fixed smooth pulley as shown in the figure. The coefficient of friction between the block A and the horizontal table is mu=0.2 . If the block A is just to slip, find the ratio of the masses of the blocks.

A boy revolves two balls each of mass 100 gm and tied with strings of 1 metre length each in horizontal circle as shown in figure. If the speed of outermost ball is 6 m/s , then tension in string-1 is-
