This is College Physics Answers with Shaun Dychko. The Bohr radius is Planck's constant squared divided by 4 times <i>π</i> squared times the mass of an electron times Coulomb's constant times the elementary charge squared. So we substitute for each of these constants and then get our answer; 5.29 times 10 to the minus 11 meters is the Bohr radius.
