Question
Sitting at 'Mark Zero' on some tiny number line, you measure an Electric Field, pushing strongly to the right with an approximate strength of 50 Newtons/Coulombs. You realize the field has been created by a pair of protons (an 'alpha particle') sitting 8 times 10^-6 meters away - on your left. You have no interest in this Electric field: You did not ask for one, and you refused to be forced in any direction. You don't move a millimeter; you simply lake out a single electron you happen to have and you place it 4 times 10^-6 meters to your left. As planned, effects from the single electron cancels those from the pair of protons and electrostatic Held plummets to zero.Explanation / Answer
True.
Force due to both protons F1 = k (2q)/(8*10^-6) N Pushing away from 2q
Force due to an electron F2 = k (q) / (4 * 10^-6) N Pulling towards charge q
As we can see, the net force cancels each other. So net force zero.
