Antigravity: The largest electric field strength you can create in air before dielectric breakdown (a spark) occurs is about 3.0 × 106 V/m. A physicist has created anelectric field with this strength – pointing directly downward – between a set of parallel plates that are 22 cm apart. She is using this system to study chargedmicroscopic oil droplets. The droplets are created with a nearly uniform mass of 5.0 x 10-13kg.When the field is off, all of the droplets fall under their own weight. When the field is switched on, the physicists observes that some droplets accelerate upward at arate of 0.78 m/s2. What is the net charge on these droplets?Report your result in SI units and as a number of extra or missing electrons.E
