When sugar is poured from the box into the sugar bowl,  the rubbing of the sugar grains creates a static electric charge that repels the grains, and causes sugar to flying in all different directions. If two sugar grains each acquire a charge of  5.8*10^-14C at a separation of 2.0*10^-8m with what force will they repel each other?  (Using Coulomb's Law)

• .07569N
• 1.5138*10^-9N
• 1.21104*10^-32 N
• 1.5138*10³¹
