Why did Thomson atom model fail?

According to Thomson's model, every atom consists of a positively charged sphere of radius 10^(-10)m in which entire mass and positive charge of the atom are uniformly distributed. Inside the sphere, electrons are embedded like seeds in a watermelon. According Rutherford, entire positive charge and mass of the atom are concentrated in a tiny central core of the atom, which is called atomic nucleus. Size of nucleus ~~10^(-15)m . The nucleus contains proton and neutrons. Negatively charged electrons revolve around the nucleus in circular orbits. The size of atom is of the order of
