Ablock weighing 400 kg rests on a horizontal surface and supports on top of it ,another block of weight 100 kg which is attached to a vertical wall by a string 6 meter long and 5 meter away from the wall. find the magnitude of the horizontal force f, applied to the lower block that shall be necessary so that slipping of 100 kg block occurs. (take coefficient of friction for both contacts =0.25 )
