Estimate the temperature needed to achieve the fusion of deuterium to make an alpha particle. The energy required can be estimated from Coulomb's law. You can use the form E=9.0x10^9 (Q1Q2/r). Q=1.6x10^-19 C for a proton and r=2x10^-15 m for the helium nucleus. The units for the proportionality constant in Coulomb's law is J*m/C^2.
