Rocket observations show that dust particles in Earth’s upper atmosphere are often electrically charged. (a) Find the distance separating two dust particles if each has a charge of +e and the Coulomb force between them has magnitude 1.00 × 10 −14 N. (b) Calculate the mass of one of the dust panicles if this Coulomb force would accelerate it at 4.50 × 10 8 m/s 2 . (In the upper atmosphere, effects from other nearby charges typically result in a small net force and acceleration.)
