(i)Most of the alpha-particles pass by the foil straight away undeflected.
(ii)Some of them are deflected by small angles.
(iii)A few alpha-particles (1 in 1000) are deflected by the angle more than 90o.
(iv)A few alpha -particles (very few) returned back i.e. deflected by 180o.
(v) Distance of closest approach (Nuclear dimension)
After Rutherford's scattering of alpha-particles experiment, following conclusions were made as regard as atomic structure:
(a) Most of the volume and every of the charge of an atom concentrated in a very minute region is known as atomic nucleus.
(b) Nucleus has positive charge and it's size is of the order of 10–15 m ≈1 Fermi.
(c) In a molecule there is maximum empty space and the electrons revolve around the nucleus in the similar way as the planets revolve around the sun.
A charge of 111 pC is uniformly distributed throughout the volume of an isolated sphere of diameter 40 cm. Calculate the electric field at the following distances from the centre o
