A light string passing over a smooth light pulley connects two blocks of masses m_(1) and m_(2) (vertically).If the acceleration of the system is g/8 then the ratio of masses "m_(1)" to "m_(2)" is "(" take "m_(1)>m_(2)]

Two bodies of masses m_1 and m_2 are connected by a light string going over a smooth lilght pulley at the end of an incline. The mass_1 lies on the incline m_2 hangs vertically. The system is t rest. Find the angle of the incline and the fore exerted by the incline on the body of mass m_1.

Two bodies of massless string passing over a frictionless pulley. The acceleration of the system is (g=9.8m//s^(2))

A block of mass m_(1)=2 kg is kept on a smooth horizontal table. Another block of mass m_(2)=1 kg is connected to m_(1) by a light inextensible string passing over a smooth pulley as shown in the figure. If the blocks are released, what will be the (a) acceleration of each block (b) tension in the string?

Two bodies of masses 2kg and 3kg are connected by a very light string passed over a clamped light smooth pulley. If the system is released from rest, find the acceleration of the two masses and the tension in the string (g=10m s^(-2) )

A pulley is mounted on a stand which is placed over a weighing scale. The combined mass of the stand and the pulley is M_(0) . A light string passes over the smooth pulley and two masses m and M (gt m) are connected to its ends (see figure). Find the reading of the scale when the two masses are left free to move.

Two masses 2 kg and 4 kg are connected at the two ends of light inextensible string passing over a frictionless pulley. If the masses are released, then find the acceleration of the masses and the tension in the string.
