Statement 1 (S1): According to Rutherford, there is a positively charged centre in an atom called the nucleus.
Statement 2 (S2): According to Thomson, the electrons revolve around the nucleus in circular paths.

The correct option is A S1 is true but S2 is false

According to Rutherford, there is a positively charged centre in an atom. He called it the nucleus of the atom.

So, S1 is true.

Thomson postulated that the electrons are embedded inside the positively charged sphere. However, Rutherford postulated that the electrons revolve around the nucleus in circular paths.

So, S2 is false.
