A particle of mass m makes a head-on elastic collision with a particle

1.	A particle of mass m makes a head-on elastic collision with a particle of mass 2m initially at rest. The velocity of the first particle before and after collision are given to be u_(1) and v_(1). Then which of the following statements is true in respect of this collision?
Answer» For all values of `u_(1), v_(1)` will always be less than `u_(1)` in magnitude and `\|v_(1)\|=(u_(1))/3` The fractional loss in KINETIC energy of the first PARTICLE is `8/9` The gain in kinetic energy of the second particle is `8/9th` of the initial kinetic energy of the first particle There is a net loss in the energy of the two Solution :abc Spring can be in the STATE of extension, compression, or natural length in equilibrium.

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 ?
