What force F must be applied so that m_(1) and m_(2) are at rest on m_(3) in

A large cubical shaped block of mass M rests on a fixed horizontal surface. Two blocks of mass m_(1) and m_(2) are connected by a light inextensible string passing over a light pulley as shown. Neglect friction everywhere. Then the constant horizontal force of magnitude F that should be applied to M so that m_(1) and m_(2) do not mov relative to M is:

In the figure2.217 all the surfaces are frictionless. What force F is required to be applied on the bigger block so that m_(2) and m_(3) will remain at rest on it.

Two blocks of mass m_(1) = 6 kg and m_(2) = 3kg are as shown in the diagram. Coefficient of friction between m_(1) and m_(2) and between m_(1) and m_(2) and between m_(1) and the surface is 0.5 and 0.4 , respectively . The maximum horizontal force that can be applied to the mass m_(1) so that they move without separation is

For the system shown in fig, there is no friction anywhere. Masses m_(1) and m_(2) can move up or down in the slots cut in mass M. Two non-zero horizontal force F_(1) and F_(2) are applied as shown. The pulleys are massles and frictionless. Given m_(1) != m_(2) Let F_(1) and F_(2) are applied in such a way that m_(1) and m_(2) do not move w.r.t. M. then what is the magnitude of the acceleration of M? Let m_(1) gt m_(2) .
