Question

Use the following figure to answer the next problem:  The electric field versus distance for a charge is plotted above. Use the reference point
V = 0 at r$\rightarrow$infinity.
-The work required to move a charge, q = +e from infinity to r = 2 m is

Quizplus · Accepted Answer

The work required to move a charge q from infinity to a distance r is given by W = qV, where V is the potential difference between infinity and distance r. From the graph, we can see that the potential difference between infinity and r = 2 m is 2000 V. Therefore, the work required to move the charge q = F1F1F1S1F1F1F10e is W = qV = (1.6 x 10^-19 C)(2000 V) = 320 x 10^-17 J = 2000 eV. Thus, the best choice is B.
