The structure of NH3 the molecule is approximately that of anequilateral tetrahedron, with three H+ ions forming the base and anN3- ion at the apex of the tetrahedron. The length of each side is1.64 10-10 m. Calculate the electric force that acts on each ion.(Let the H+ ions be in the x-y plane with H1 at (0, 0, 0), H2 at(a, 0, 0), and H3 at (a/2,[a*b^(1/2)]/2,0). The N3- ion, withcharge q4 in our notation, is then at(a/2,a/[2sqrt(3)],asqrt(2/3))
where a = 1.64 10-10 m. To simplify our calculations we'll setke2/a2 = C = 8.56 10-9 N. Use the following variable as necessary :C.)

Find the force for H1, H2, H3 and N3-
