Question

two alpha particles separated by a distance r.force between them is equal to weight of electron.find r​

Answer 1

Answer:

q=2e =2×1.6×10 −19 =3.2×10 −19 C Distance between the α−particles,d=8.2fermi=8.2×10 −15 m ∴ Coulomb force between the two α−particles,F= 4πϵ 0 1 d2 q1 q2=

(8.2×10 −15 ) 2 9×10 9 ×(3.2×10 −19) (3.2×10 −19 )≈13.7≈14N
