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 4.156 N/C, how long would it take this proton to travel a distance of 649.72m 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

Electric Charges and Fields

One of the fundamental properties is the electromagnetic property. Charge cannot be destroyed by any process and this contributes formally to the law of charge conservation.
