All surfaces assumed to be frictionless calculate the horizontal force F that must be applied so that m_(1) and m_(2) do not move relative to m_(3) is :–

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

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.

Blocks are in contact on a frictionless table. A horizontal force F=3N is applied to one block as shown. The force exerted by the smaller block m_(2) on block m_(1) is :

Blocks are in contact on a frictionless table. A horizontal force F=3N is applied to one block as shown. The force exerted by the smaller block m_(2) on block m_(1) is :

Blocks are in contact on a frictionless table. A horizontal force F = 3N is applied to one block as shown. The force exerted by the smaller block m_(2) on block m_(1) is-

In the adjoining figure all surface are frictionless . What force F must by applied to M_(1) to keep M_(3) free from rising or falling?

In the adjoining figure all surface are frictionless . What force F must by applied to M_(1) to keep M_(3) free from rising or falling?

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:
