1.	Explain the concept of nuclear binding energy. Draw a curve between mass number and average binding energy per nucleon.What conclusions do you draw from this curve ?
Answer» Solution :Binding energy of a nucleus is the energy with which nucleons are bound in the nucleus. It is also the work REQUIRED to be done to separate the nucleons at INFINITE distance apart from nucleus so that they do not interact with each other. CONCLUSION. (i) There exists peaks in the curve corresponding to mass number `A=4, 12, 16, 20`. The nuclei corresponding to those mass number `""_(2)He^(4), ""_(6)C^(12), ""_(8)O^(16), ""_(10)Ne^(20)`, the peaks indicate that these nuclei have more binding energy per nucleon than their immediate neighbours. So they are more stable nuclei. (ii) Binding energy per nucleon is smaller for light and heavier nuclei i.e. light and heavier nuclei are less stable than middle one. In order to attain higher value of binding energy per nucleon, the heavier nuclei may split into lighter nuclei (process of fission) and lighter nuclei may unite to form heavier nuclei (process offusion). In both of these NUCLEAR processes, a large amount of energy is released.

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 ?
