Answer : The subatomic particle found in the nucleus with a positive charge is the proton.
Explanation :
As we know that,
Atom : An atom is the smallest unit of a matter that consist of three subatomic particles that are electrons, protons and neutrons.
The protons and the neutrons are located inside the nucleus or center of the nucleus where the mass of the an atom is concentrated and the electrons are located around the nucleus.
The protons are positively charged, the electrons are negatively charged and the neutrons are neutral that means it has no charge.
Hence, the subatomic particle found in the nucleus with a positive charge is the proton.
