Statement-I : In Rutherford's gold foil experiment, very few `alpha`-particles are deflected back.
Because
Statement-II : Nucleus present inside the atom is heavy.

Assertion (A) : In rutherford's gold foil experiment, very few alpha particle are deflected back Reason (R ) : Nuclear present inside the atom is heavy

In Rutherford's gold foil experiment, the scattering of alpha -particles takes place. In this process:

In Rutherford experiment ,very few of the alpha particles scatter through large angles. Why ?

Assertion : In Rutherford's alpha -particle scattering experiment, most of the alpha -particles were deflected by nearly 180^(@) . Reason : The positive charge of the atom is spread throughout the atom that repelled and deflected the positively charged alpha -particles.
