1.	a) The peak voltage of an a.c. supply is 300 V. What is the rms voltage ? (b) The rms value of current in an a.c. circuit is 10 A. What is the peak current ?
Answer» Solution :(a) `therefore V_(m) = 300 V`, HENCE `V_(rms) = V_(m)/sqrt(2) = 300/sqrt(2) = 212.1` V (b) As `I_(rms) = 10A`, hence `I_(m) = sqrt(2). I_(rms) = sqrt(2) xx 10 = 14.14 A = 14.1` A

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 ?
