Is photon drive reaction less propulsion?

Question

If photon dont have mass how can produce thrust, it seems that violate Newton 3. law?

If light dont have mass how can push solar sail?

Answer 1

It will not violate Newton's third law, since although photons have no mass, they still have momentum given by $$p=\frac Ec$$ where $E$ is energy and $c$ the speed of light.
