When sugar is poured from the box into the sugar bowl, the rubbing of sugar grains creates a static electric charge that repels the grains, and causes sugar to go flying out in all directions. If each of two sugar grains acquires a charge of 3.0 x 10-11 C at a separation of 8.00 x 10-5 m, with what force will they repel each other ?

You can use Coulomb's Law which says:
[tex]F_s = \frac{Kq_1q_2}{r^2} [/tex]

Plug in given values:
[tex]F_s = \frac{(9*10^9)(3*10^{-11})(3*10^{-11})}{(8*10^-5)^2} [/tex]

When you plug that into a calculator, you get:
[tex]F_s = 1.27 * 10^{-3}[/tex]

That's your answer.
