For scattering by an 'inverse square field' (such as that produced by a charged nucleus in Rutherford's model) the relation between impact parameter b and the scattering angle theta is given by b (Ze^2 cot (theta/2))/(4 pi epsi_0 ((mv^2)/(2))) a. What is the scattering angle for b =0? b. For a given impact parameter h, does the angle of deflection increase or decrease with increasing energy? c .What is the impact parameter at which the scattering angle is 90^@ for Z = 79 and initial energy of 10 MeV? d. Why is it that the mass of the nucleus does not enter the formula above but the charge does? e. For a given energy of the projectile, does the scattering angle increase or decrease with decrease in impact parameter?

Light is incident normally on a small plane surface. If the surface is rotated by an angle of 30 about the incident light, does the illuminance of the surface increase, decrease or remain same ? Does your answer change if the light did not fall normally on the surface ?

A block of mass m is pushed against a spring of spring constant k fixed at the end to a wall. The block can side on a frictionless table as shown in figure. The natural length of the spring is L_0 and it is compressed ti half its natural length when the block is relesed. Find teh velocity of the block aa s function of its distance x from the wall .

A light spring of spring constant k is kept compressed between two blocks of masses m and M on a smooth horizontal surface. When released, the blocks acquire velocities in opposite directions. The spring loses contact with the blocks when it acquires natural length. If the spring was initially compressed through a distance x find the final speeds of the two blocks.

Assertion : The elastic spring force arises due to the net attraction or repulsion between the neighbouring atoms of the spring when it is elongated of compressed. Reason : The laws of derived forces such as spring force, friction force are independent of the laws of fundamental forces in nature.
