Question
Physics 21S Short Answer (25 points total): This plot depicts equipotential lines in a region of space. Calculate the amount of work required to move a proton along the following paths (you may assume a straight line in between each point). (15 points, 5 each) Path #1 (A-G-B) iov 20v 30v av Path W2 (A-1-H) Path #3 (B-G-H) (5 points) If the proton above is now bound to a neutron, making a new particle, how much work is required to move the new along Path #1 (A-G-B)? Circle the correct answer and provide a short justification. You may assume t mass of the neutron is equal to the mass of the proton. more energy less energy the same energy Because... (5 points) If an electron were placed at rest at Point C, which point would it pass closest to? Circle the correct answer and provide a short justification. Point A Point B Point G It will not move. Because.. 13 of 18Explanation / Answer
We know that work done is
W=q(V2-V1)
So it does not depend on the path taken it only depends on the initial and final positions
Path 1
W=1.6*10-19(50-10)
W=64*10-19J
Path 2
W=1.6*10-19*40
W=64*10-19J
Path 3
It will be zero, as initial and final positions are of both same potential.
It will be the same energy as we have seen that work done only depends on the charge and potential difference and neutron have zero charge , so it doesn't affect the work done.
It will move towards point B.
