You Answered Correct Answer A line of charge is placed along the negative x axis from x=-0.4m to x=0. The charge is uniformly distributed with linear charge density 3.06pC/m. A proton is released from rest at a point on the positive x axis 2.53m. When the proton has a speed of 472.1m/s, how far will it have moved (in m}? 1.0975 margin of error +/-1%
Two large parallel copper plates are 7.39 cm apart and have a uniform electric field of magnitude E = 3.44 N/C between them (see the figure). An electron is released from the negative plate at the same time that a proton is released from the positive plate. Neglect the force of the particles on each other and find their distance from the positive plate when they pass each other. Positive Negative plate plate P E Number i Units
