Suppose you are given a chance to repeat the alpha-particle scattering

1.	Suppose you are given a chance to repeat the alpha-particle scattering experiment using a thin sheet of solid hydrogen in place of the gold foil. (Hydrogen is a solid at temperatures below 14 K.) What results do you expect?
Answer» Solution :If in Rutherford.s alpha-PARTICLE scattering experiment we USE a thin SHEET of solid hydrogen in place of GOLD foil then no large angle scattering of alpha-particles is possible. We know that nucleus of hydrogen atom is a proton having a mass of only `1.67 xx 10^(-27)kg`, whereas mass of alpha-particle is FOUR times the mass of proton `(6.64 xx 10^(-27)kg)`. As the scattering particle is more massive than the target nucleus, the alpha-particle would not bounce back even for a head-on collision. The situation is similar to a football colliding with a tennis ball at rest and in such a situation we do not expect large angle scattering.

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 ?
