According to classical physics, potential energy of electron moving in circular orbit of radius r is………

Options

A. `-(1)/(4piin_(0)).(Ze^(2))/(r)`
B. `-(1)/(8piin_(0)).(Ze^(2))/(r)`
C. `-(1)/(4pi).(Ze^(2))/(r)`
D. `(1)/(8piin_(0)).(Ze^(2))/(r)`

Answer

A

Explanation

Potential energy,
`U=(1)/(4piin_(0)).(q_(1)q_(2))/(r)impliesU=(1)/(4piin_(0)).((Ze)(-e))/(r)`
`:.U=-(1)/(4piin_(0)).(Ze^(2))/(r)`
