Question
Burning coal, which is how many power plants generateelectricity, releases a number of harmful byproducts. Particulatepollution (i.e., soot or smoke) is the most visually obvious.Modern coal-burning power plants make use of electrostaticprecipitators (ESPs) to remove most of the particulate pollution.As the hot, impure air heads out of the plant, it passes through anarea where soot particles can pick up some electric charge. The airthen passes through an area with a strong electric field to pullthe pollutant particles away to an area where they can be safelyremoved.

The airthen passes through an area with a strong electric field to pullthe pollutant particles away to an area where they can be safelyremoved. If this charged soot particle is now isolated(that is, removed from the electric field described in the previouspart), what will be the magnitude E of the electric field due to the particle at distance 1.00 meterfrom the particle?Explanation / Answer
ADDITIONAL RESULT: If {Q = 7.25e-16 C}, electric field "E" would have magnitude: E = (8.988e+9)*(7.25e-16) = 6.516e-6 V/m .
