1.	A thin equiconvex spherical glass lens (mu=3//2) of radius of curvature 30 cm is placed on the x-axis with its optical centre at x=40 cm and principal axis coinciding with the x-axis. A light ray given by the equation 39y=-x+1 ( x and y are is incident on the lens, in the direction of positive (in cm) X-axis. Then choose the correct alternative(s)
Answer» The EQUATION of REFRACTED ray is `39y=x+1` The equation of refracted ray is `130y=x-170` The equation of refracted ray if space on RIGHT side of the lens is filled with a liquid of refractive index 4/3 is `390y+x+360=0` The equation of refracted ray if space on right side of the lens is filled with a liquid of refractive index 4/3 is `390y-x+350=0` ANSWER :B::C

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 ?
