Define the term resolving power of a telescope. How does it get affect

1.	Define the term resolving power of a telescope. How does it get affected on (i) increasing the aperture of the objective lens, (ii) Increasing the focal length of the objective lens ?
Answer» SOLUTION :For the term RESOLVING power. resolving power of a telescope `=(A)/(1.22lamda)`, where A is the APERTURE of telescope OBJECTIVE and `LAMDA` the wavelength of light. (i) On increasing the aperture of the objective lens the resolving power is increased in the same ratio. (ii) Focal length of objective lens has no effect on resolving power of telescope.

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 ?
