Two samll sphere each of mass `m` connected by a string of length 2l are kept on a smooth horizontal surface. A vertical force `F` is applied at the middle of the string. What is maximum value of `F` for which the sphere do not lose contact with the surface?

Two small spheres each of mass m connected by a string of length 21 are kept on a smooth horizontal surface.A vertical force F is applied at the middle of the string. What is the maximum value of F for which the spheres do not lose contact with the surface ?

Four blocks each of mass M connected by a massless strings are pulled by a force F on a smooth horizontal surface, as shown in figure.
