1.	A point object moves along the principal axis of a convex lens of focal length f such that its realimage, also formed on the principal axis at a distance (4f)/(3)(at t=0) moves away from the lens with uniform velocity alpha. Find the velocity of the point object as a function of time t.
Answer» `((F)/(f+ ALPHA t))^2 alpha` `((alpha)/(R +alpha t))^2` `((r//3 + alpha t^2)/(f))^2 alpha ` `((f)/(f/3 +alpha t ) )^2 alpha` 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 ?
