Question

Burning coal, which is how many power plants generate electricity, releases a number of harmful byproducts. Particulate pollution (i.e., soot or smoke) is the most visually obvious. Modern coal-burning power plants make use of electrostatic precipitators (ESPs) to remove most of the particulate pollution. As the hot, impure air heads out of the plant, it passes through an area where soot particles can pick up some electric charge. The air then passes through an area with a strong electric field to pull the pollutant particles away to an area where they can be safely removed. If this charged soot particle is now isolated (that is, removed from the electric field described in the previous part), what will be the magnitude of the electric field due to the particle at distance 1.00 meter from the particle?

Explanation / Answer

You don't. You have failed to give any magnitude: electric field, drag force. Your car does miles per hour, how long to go miles? Answer this and you will have figured out the **** in yours.
