1.	A particle of mass 3 m at rest decay Into two particles of masses m and 2m having non-zero velocities. What is the ratio of the de-Broglie wavelengths of the particle (lambda_(1)//lambda_(2)).
Answer» 1:1 1:2 3:2 2:1 Solution :From CONSERVATION of linear momentum both the PARTICLES will have equal and OPPOSITE momentum. The de-Broglie wavelength is GIVEN by `lambda=h//p``therefore``lambda_(1)//lambda_(2)=1`

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 ?
