1.	Answer question (a) - (e) on the basis of data given in the following table and your understanding of the relation studied concepts : In a school laboratory following lenses are available : All these lenes are converging lenses. Which two lenses would you select to design a compound microscope and why?
Answer» Solution :To design a COMPOUND microscope we shall select lens no. 10 (f = 2 cm and APERTURE A = 1 cm) as the objective lens and lens no. 7 (f = 3 cm and aperature A = 2 cm) as the eyepiece. It is due to the FACT that both the lenses in a compound microcope be of small focal length and small aperature. However, comparatively focal length and aperture of objective is even smaller than that of eyepiece.

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 ?
