Q.1 Consider a smooth inclined plane that is making an angle of 60 with the horizontal axis. An object of mass 11 kg is supported on this plane with a force F making an angle of 30 degree with the inclined plane. Find the force F and the reaction of the plane on the object. Q.2 A set of four uniform rods of equal length are smoothly joined together to form a rhombus OPQR, placed in a vertical plane. O rests on the horizontl plane with OQ being vertical. The ends P and R are joined together through a light string to keep the rhombus in shape such that MZPOQ = 0. Find the tension in the string joining P with R.
