A 10 −15  meter is equivalent to one Fermi. A proton has a radius of 1.3 Fermis. The radius of a proton in meters is 1.3× 10 −15 m  .
1 fermi = 10 −15  m
Proton’s radius =1.3× 10 −15 m   .
Therefore, standard form of radius of the proton is 1.3× 10 −15 m  .
Hence, the correct answer is 1.3× 10 −15 m  .
