- Why can't we really draw a true representation of an electric field? Can there be an electric field at a point where there is no charge? Can there be a charge at a place where there is no field? Please write a one or two-sentence answer to each of these questions.A proton has a mass of about 1.673x10-27kg. If an electron is placed in a region of space within which a constant electric field exists with magnitude 4.878 N/C, how long would it take this proton to travel a distance of 218.64m in units of ms (milliseconds)? Assume the proton does not collide with anything along the way. Hint: You will need to use the kinematic relationships for linear motion that we learned back in PHY 2010. This results of this problem show you that small charges like protons, and electrons too, move great distances in a short amount of time under very small external electric fields - if those charges are in a vacuum - otherwise, they quickly strike a nearby charge. Note: It is understood that the unit of your answer is in milliseconds, however do not explicitly include units in your answer. Enter only a number.What is electric charge? Give its basic properties.
