`m_(A) = 1 kg, m_(B) = 2 kg, m_(C) = 10 kg`

Given m_(A) = 30 kg, m_(B) = 10 kg, m_(C) = 20 kg . Between a & B mu_(1) = 0.3 , between B & C mu_(2) = 0.2 & between C & ground mu_(3) = 0.1 . The least horizontal force F to start motion of ant part of the system of three blocks resting upon one another as shown below is : (Take g = 10m//s^(2) )

In the figure-2.205 shown in blocks A, B and C has masses m_(A)= 5 kg, m_(B) = 5 kg and m_(C )= 10kg respectively, find the acceleration of the three blocks. Assume all pulleys and strings are ideal. (Take g = 10m//s^(2) )

In the figure shown, m_(1) = 10kg, m_(2) = 6kg, m_(3) = 4kg. If T_(3) = 40 N, T_(2) = ?

In the system shown in fig., all pulleys are mass less and the string is inextensible and light. (a) After the system is released, find the acceleration of mass m_(1) (b) If m_(1) = 1 kg, m_(2) = 2 kg "and" m_(3) = 3 kg then what must be value of mass m_(4) so that it accelerates downwards?

Three block are connected as shown, on a horizontal frictionless table and pulled to the right with a force T_(3) = 60 N. If m_(1) = 10 kg , m_(2) = 20 kg and m_(3) = 30 kg, the tension T_(2) is-

Three block of masses m_(1) = 10kg, m_(2) =20 kg and m_(3) = 30kg are on a smooth horizontal table ,connected to each other by light horizontal string. A horizontal placed force F = 60N is applied to m_(3) , towards right find (a) tension T_(1) and T_(2) and (b) tension T_(2) if all of a sudden the string between m_(1) and m_(2) snaps.

In the system of connecting blocks, m_(A) =1kg, m_(B)=2kg and m_(C)=2kg .The inclined plane is smooth while the friction coefficient between block B and horizontal ground is mu .Mark the correct options.(g=10m s^(-2) )
