Answer:
When an electron moves in a circular orbit at a distance r from a proton,
its potential energy is given by -q2/(4πε0r). By definition of potential enegy,
this amount of energy is given to eletron to bring it from infinity to the point which is
at a distance r from the proton. Hence same amount of energy should be given to
move the electron to infinity.
To escape to infinity, the energy must be supplied to the electron is q2/(4πε0r)
