Solution
The correct option is A P
The following are the observations of the gold foil experiment:
(i) Most of the fast moving α-particles passed straight through the gold foil.
(ii) Some of the α - particles were deflected by the foil by small angles.
(iii) Surprisingly, a few α-particles had nearly 1800 angle of deflection.
