A plank with a uniform sphere placed on it resting on a smooth horizontal plane. Plank is pulled to right by a constant force F . If sphere does not slip over the plank. Which of the following is incorrect?

A uniform rod is resting freely over a smooth horizontal plane. A particle moving horizontally strikes at one end of the rod normally and gets stuck. Then

A uniform rod is resting freely over a smooth horizontal plane. A particle moving horizontally strikes at one end of the rod normally and gets stuck. Then

A particle is resting over a smooth horizontal floor AT t = 0, a horizontal force starts acting on it. Magnitude of the force increases with time F = kt, where k is a constant. The two curves are drawn for this particle as shown

A uniform rope of length 10m is on a smooth horizontal surface. It is being pulled by a horizontal force of 20N at one end. The ratio of tension at a distance of 4m from force end to tension at a distance of 4m from free end is

A uniform rope of length 5m is on a smooth horizontal surface. It is being pulled by a horizontal force of 20 N at one end. The ratio of tension at a distance of 2m from force end to tension at a distance of 2m from free end is,
