Question

What happens to an electron revolving in a circular orbit according to classical electromagnetic theory?

Options

• It has no acceleration.

• It remains in a stationary state without emitting radiant energy.

• It makes a transition to an orbit of lower energy.

• It is constantly accelerated.

Answer 1

An electron revolving in a circular orbit is constantly accelerated. Classical electromagnetic theory predicts that an accelerating charged particle emits electromagnetic radiation.
