1.	Two capacitors of capacitance 600 pF and 900 pF are connected in series across a 200 V supply .Calculate the effective capacitance of the combination.
Answer» Solution :Given: `C_1`=600 PF , `C_2` =900 pF V=200V `1/C_S=1/C_1+1/C_2=(C_1+C_2)/(C_1+C_2)` `C_S=(C_1C_2)/(C_1+C_2)=(600xx900)/(600+900)=(54xx10^4)/(15xx10^2)=5400/15`=360 pF

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 ?
