Problem: An atomic nucleus has a charge of +40e. An electron is 10-9 m from the nucleus. What is the force on the electron?A) 2.9 nN B) 9.2 nNC) 3.7 nN D) 1000 C E) 6.8 nN
FREE Expert Solution
From Coulomb's law:
- k = 8.99 × 109 Nm2/C2 (Coulomb's Constant)
- q1 = 40 (1.6 × 10-19) C
- q2 = 1.6 × 10-19C
- r = 10-9m
Substituting gives:
