Thomson’s atomic model explained the overall neutrality of an atom. Its assumption that the total mass of an atom is uniformly distributed all over the atom was inconsistent with some of the experimental results. Rutherford’s gold foil experiment of scattering α-particles revealed that most of the space in an atom is empty contradicted Thomson’s atomic model. Thus, it was found that the plum pudding atomic model was insufficient to explain the structure of an atom.
The limitations of Thomson’s atomic model triggered further researches for establishing the structure of an atom. The plum pudding atomic model lacked experimental evidence and hence Rutherford conducted many experiments in order to determine the structure of an atom.

a) It could not explain the result of the scattering experiment performed by Rutherford
b) However, it was later found that the positively charged particles reside at the centre of the atom called the nucleus, and the electrons revolve around the nucleus, which was contradiction to JJ Thompson's model.
Hope this will be helpful :)
