An electron is moving around the nucleus of a hydrogen atom in a circular orbit of radius r . The coulomb force F between the two is: ( . where .K= 1 4 ₀ )

Options

  1. AK e^2 r^2 r
  2. B-K e^2 r^3 r
  3. CK e^2 r^3 r
  4. D-K e^2 r^3 r

Correct answer

D. -K e^2 r^3 r

Step-by-step solution

The charge on hydrogen nuclear q₁ aligned & =+v e & Coulomb's force F=K q₁ q₂ r^2 & =K (+e)(-e) r^2 =- k e^2 r^2 r aligned
