Carbon-12 and oxygen-16 can be considered to be three … WebbA helium nucleus contains two protons. In a model of the helium nucleus, each proton is considered to be a charged point mass. The separation of these point masses is assumed to be 2.0 × 1 0 − 15 m. For the two protons in this model, calculate the electrostatic force.
