Question

Two helium nuclei are seperated by a distance 6nm what is electrostatic repulsion

Answer 1

Answer:

According to coulomb's law,

                            F =(k Q q)/$r^{2}$

         

                          F = ( 9 x 10^9) (9 x 10^9) (9 x 10^9) / ( 6 x 10^-9)²

                          F =   25.6 x 10^-12

                           F = 25.6 pN
