A uniform electric field has a magnitude of 2.1E3 Newtons/Coulombs. In a vacuum, a proton begins with a speed of 2.0E4 meters/seconds and moves in the direction of this field. Find the speed of the proton after it has moved a distance of 1.0mm.© BrainMass Inc. brainmass.com February 24, 2021, 2:19 pm ad1c9bdddf
The speed of the proton is low enough that we need not consider relativistic effects.
<br>Recall that the charge on a proton is: 1.602 E-19 C
<br>So, the electric field will exert a force on the proton of:
<br>(2.1E3 N/C)(1.602E-19 C) = 3.3642E-16 N
<br>as the ...
