Precise measurements of physical quantities are a need of science. For example, to ascertain the speed of an aircraft, one must have an accurate method to find its positions at closely separated instants of time. This was the actual motivation behind the discovery of radar in World War II. Think of different examples in modern science you can, give a quantitative idea of the precision needed.

Two positrons (e+) and two protons (p) are kept on four corners of a square of side a as shown in figure. The mass of proton is much larger than the mass of positron. Let q denotes the charge on the proton as well as the position then the kinetic energies of one of the positrons and one of the protons respectively after a very long time will be-

Figure shows a pulley block system in which a block A is hanging one side of pulley and an other side a small bead B of mass m is welded on pe=ulley. The moment of intertia of pulley is I and the sytem is in equilibrium position when bead is at an angle alpha from the vertical. If the system is slightly disturbed from its equlibrium position, find the time period of its oscillations.
