A system consists of two cubes of mass `m_(1)`, and `m_(2)` respectively connected by a spring of force constant k. force (F) that should be applied to the upper cube for which the lower one just lifts after the force is removed, is

Two blocks of mass m_(1) and m_(2) are connected by a spring of force constant k. Block of mass m_(1) os pulled by a constant force f_(2) [see fig 4E.19 (a)] find the maximum elongation in the spring .

Two disks of masses m_(1) and m_(2) are connected by a spring of force canstant k. The lower disk of mass m_(2) lies on a table and the upper disk is vertically above it. What vertical force F should be applied to the upper disk so that when the force is withdraw, the lower disk is lifted off the table?

Two blocks of masses m_(1) and m_(2) being connected with a light spring of stiffness k are driven with forces F_(1) and F_(2) on a smooth plane .find the value of spring force .

Two blocks m_(1) and m_(2) are connected by a massless spring of force constant k F_(1) and F_(2) are two forces acting on m and m_1 and m_2 as shown. The arrangement is on a horizontal plane.

A block of mass M is kept on a rough horizontal surface and is attached with massless spring of force constant k .The minimum constant force applied on the other end of the spring to lift the block is

A block of mass m is kept on a rough horizontal surface and is attached with a massless spring of force constant k. The minimum constant force applied on the other end of the spring of lift the block is

A system consists of t wo identical masses A and B of mass m each connected to ends of a massless spring of force constant k as shown in figure. The minimum force F applied vertically downward on A, such that on its release, B will leave the floor.
