1.	The distance between two moving particles P and Q at any time is a . If v_r be their relative velocity and if u and v be the components of v_r, along and perpendicular to PQ. The closest distance between P and Q and time that elaspse before they arrive at their nearest distance is
Answer» `(a(v + v_r))/(v), a (1 + (v_r)/(u))^2` `(a)/(v + v_r), a (1 + (u)/(v_r))^2` `(av_r)/v , (av_r)/(u^2)` `(AV)/(v_r) , (AU)/(v_r^2)` Answer :D

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 ?
