a.
To find: The work done to move a second electron along the x-axis from the point
a.
Answer to Problem 41E
The work done is
Explanation of Solution
Given:
Two electrons
Calculation:
The work done can be calculated by taking integral.
Hence,
Therefore, the work done is
b.
To find: The work done to move a third electron along x-axis.
b.
Answer to Problem 41E
The work done to move a third electron is
Explanation of Solution
Given:
An electron is held fixed at points
Calculation:
The work done to move a third electron can be calculated by adding the integral calculated in first part to the integral of the given force to the point
Thus,
Therefore, The work done to move a third electron is
