Neutrons are found in the nucleus and separate the other particles so that the strong force can hold the nucleus together. which particles are positively charged and need to be separated so that they don't repel? a) electrons b) neutrons c) protons d) quarks

Answer : The correct answer is C) protons

The positively charged particle found in nucleus are protons . They need to be kept separated as if the protons of two different particles are brought together , due to same charge they will repel each other.

If electrons are considered , they carry negative charge on them and they are present outside nucleus . Neutron have no charge on it although they are present in nucleus .

Quarks are present in both neutrons and protons . They carry both positive and negative charges .

Hence we can say protons are the positively charges particles which need to be separated .
