emove fine particles from exhaust gases. This done by charging the particles and separating them with a strong electric field. Consider a positively charged particle + 1.5uC that enters an electric field with strength 4 x 10^6 N/C. The particle is traveling at 15 m/s and has a mass of 10^-9 g. What is the acceleration of the particle ? (Enter the magnitude only) 2.) what is the direction of the acceleration of the particle relative to the electric field?

Your object has mass 59.8 kg, and you ve separated the boxes of protons and electrons by a distance of 27 m. If you were to release the clump of protons from their box, how much acceleration would the clump of protons undergo due to its attraction to the clump of electrons in the other box?

You are the pilot of a spacecraft intended for travel at very high speeds. Before leaving you measure the spacecraft to be 31.4 m long and have a mass of 5.28 x 104 kg. During your travel, you pass a planet and exchange information with an observer on the planet. You are told that your spacecraft has been measured to be 28.6 m long. a. How fast is your spacecraft travelling with respect to the planet? b. You are told there is a nearby planet that is stationary with respect to the first planet. The observer on the first planet says it will take you 25 s to reach the nearby planet. How far away does your co-pilot on the spacecraft say the nearby planet is? c. How much energy was required to accelerate your spacecraft to this speed?

It has been speculated that gravity does not truly exist as a force in and of itself, but is instead a manifestation of the electrostatic force, which is the force responsible for the repulsion of like-charges and the attraction of opposite charges. Is this a credible theory? Why or why not? What experiment could a person conduct to test this theory?
