1.	Find maximum voltage across AB in the circuit shown in Fig. Assume that diode is ideal.
Answer» Solution :As the DIODE is treated ideal, its forward RESISTANCE `R_(f)=` zero. It acts as short circuit. So, `10 kOmega` is in parallel with `15kOmega` and the effective resistance across AB is `R_(AB)=(10xx15)/(10+15)=(10xx15)/(25)=6kOmega` `6kOmega` in series with `5kOmega`. `therefore` total resistance `=R_(T)=6kOmega+5kOmega=11kOmega` `V=30V` Current drawn from the battery is `I=(V)/(R_(T))=(30V)/(11kOmega)=2.72mA` `V_(AB)=IR_(AB)=2.72mA xx6kOmega=16.32V`

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 ?
