The nuclear particle carrying a charge of +1e is the

Inside the nucleus only two particles are present

1. Neutrons

2. Protons

These are also known as nucleons as combined

neutrons are chargeless and having mass same as that of protons while protons are positively charged particles and its charge is same in magnitude as that of electrons

SO the charge given here is +1e which means the magnitude of charge is same as the magnitude of electron but it is a positive charge

so it must be proton

i think it's 35 meters
