1.	From the standpoint of the corpuscular theory demostrate that the momentum transferred by a beam of parallel light rays per unit time does not depend on its spectral composition but depends only on the enegry flux Theta_(e).
Answer» Solution :The statement made in the QUESTION is not always correct. However it is correct in certain cases, for example, when light is incident on a perfect reflector or perfect absorber. Consider the former case. If light is incident at an angle `theta` and reflectef at the angle `theta`, then momentum transfered by each photon is `2(hv)/(c ) cos theta` If there are `n(v)dv` PHOTONS is FREQUENCY interval `(v,v+dv)`, then totao momentum transfered is `underset(0)OVERSET(oo)int 2N(v)(hv)/(c ) costheta dv` `= (2Phi_(e))/(c ) costheta`

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 ?
