1.	In transition from the state n = 4 to n = 3 in a hydrogen like atom results in ultraviolet region, then what should be the transition for the infrared region ?
Answer» `2to1` `3to2` `4to2` `5to4` Solution :The frequency of ultraviolet rays is high and the frequency of infrared is low. Hence the transition of electron should TAKE place in an orbit such that the order of the orbit is the HIGHEST in the given order. Such order is in option (D) `5TO 4`. This EMIT radiation in Brackett series and it is in the infrared REGION.

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 ?
