2. Relevant equations

[itex]\vec{F}[/itex] = k[itex]\stackrel{q_{1}q_{2}}{r^{2}}[/itex]

3. The attempt at a solution

6.022e23*(0.505) = 3.041e23C <-- electrons

6.022e23*(0.495) = 2.981e23C <-- protons

3.041e23 - 2.981e23 = 6e21C <-- the difference between the two charges

[itex]\vec{F}[/itex][itex]_{e}[/itex] = (9e9Nm[itex]^{2}[/itex]/C[itex]^{2}[/itex])(6e21C)[itex]^{2}[/itex] / 2.25m[itex]^{2}[/itex]

[itex]\vec{F}[/itex][itex]_{e}[/itex] = 1.44e53 N
