1.	The following table has 3 columns and 4 row. Based on table there are THREE questions. Each question has FOUR option (A), (B), (C ) and (D) ONLY ONE of these four option iscorrect Column contains a current carrying loop second column contains the value of magnetic field at point O and third column shows the value of magnetic dipole moment. Pick a combination in which magnetic field at Q is given by (mu_(0) i)/(12) (mu_(0) i)/(16 pi) sqrt(3) units
Answer» I,ii,p ii,ii,q iv,iv,p I,iv,s Solution :MAGNETIC field at the centre of a current carrying are `= ((mu_(0) i)/(2R)) ((theta)/(2 pi))` magnetic field due to current carrying striaght WIRE = `((mu_(0) i)/(4 pi R)) (sin theta_(1) + sin theta_(2))` Use these two formulas to get results in different cases. Magnetic dipole moment = Bi area of the LOOP)

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 ?
A concave lens with equal radius of curvature both sides has a focal length of 12 cm. The refractive index of the lens is 1.5. How will the focal length of the lens change if it is immersed in the liquid of refractive index 1.8 ?
