A particle of mass 5M at rest decays into two particle of masses 2 m a

1.	A particle of mass 5M at rest decays into two particle of masses 2 m and 3 m having non zero velocities. The ratio of de - broglie wavelengh of the particles is
Answer» `3//2` `2//3` `1//3` NONE of these Solution :According to LAW ofconservation of linear momentum, the PARTICLES will have EQUAL and OPPOSITE momentum. The de-Broglie wavelenght is given by `lambda=(h)/(p)` , so `(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 ?
