1.	The figure below shows the plot of (PV)/(nT) versus P for oxygen gas at two different temperatures (##ARH_EGN_PRG_PHY_C17_E01_014_Q01.png" width="80%"> Read the following statements concerning the above curves. (i) The dotted line corresponds to the ideal gas behaviour (ii) T_(1)gtT_(2) The value of (pV)/(nT) at the point where the curves meet on the y-axis is the same for all gasesWhich of the above statements is true ?
Answer» (i) only (i) and (ii) only All of these None of these Solution : (i) The dotted line in the digram shows that there is no deviation in the value of `(pV)/(nT)` for DIFFERENT temperature `T_(1)and T_(2)` for increasing pressure so , this gas BEHAVES IDEALLY .Hence , dotted line corresponds to 'ideal ' gas behaviour. (ii) At high temperature , the deviation of the gas is LESS and al low temperature the deviation of gas is more . In the graph, deviation for`T_(2)` is greater than for `T_(1) ` . Thus , (iii) Since , the two curves intersect at dotted line so, the value of `(pV)/(nT)` at that point on the the y-axis is same for all gases.

A wire is bent to form a semicircle of the radius a. The wire rotates about its one end with angular velocity omega . Axis of rotation is perpendicular to the plane of the semicircle . In the space , a uniform magnetic field of induction B exists along the aixs of rotation as shown in the figure . Then -
A massless non conducting rod AB of length 2l is placed in uniform time varying magnetic field confined in a cylindrical region of radius (R gt l) as shown in the figure. The center of the rod coincides with the centre of the cylin- drical region. The rod can freely rotate in the plane of the Figure about an axis coinciding with the axis of the cylinder. Two particles, each of mass m and charge q are attached to the ends A and B of the rod. The time varying magnetic field in this cylindrical region is given by B = B_(0) [1-(t)/(2)] where B_(0) is a constant. The field is switched on at time t = 0. Consider B_(0) = 100T, l = 4 cm(q)/(m) = (4pi)/(100) C//kg. Calculate the time in which the rod will reach position CD shown in the figure for th first time. Will end A be at C or D at this instant ?
