Answer:
The charge of each argon nuclei is 2.88e-18 C. Thus, the force between two argon nuclei 1nm apart is 7.475e-8 Newtons.
Thanks
Charge on an argon nuclei is, q = +18e = 18 × 1.6 × 10-19 C
Distance between the two argon nuclei, r = 10-9 m
So, force of repulsion is, F = kq2/r2
=> F = (9 × 109)(18 × 1.6 × 10-19)2/(10-9)2
=> F = 2.592 × 10-9 N
