Suppose an electron was bound to a proton, as in the hydrogen atom, but by the gravitational force rather than by the electric force. part awhat would be the radius of the first bohr orbit? part bwhat would be energy of the first bohr orbit?

Two lasers are shining on a double slit, with slit separation d. laser 1 has a wavelength of d/20, whereas laser 2 has a wavelength of d/15. the lasers produce separate interference patterns on a screen a distance 5.30 m away from the slits. part a which laser has its first maximum closer to the central maximum? view available hint(s) which laser has its first maximum closer to the central maximum? laser 1 laser 2
