Question
What is the work done in moving a test charge q through a distance of 1 cm along the equatorial axis of an electric dipole?
Solution
Work done is given by,
W = qV
Since, the equitorial plane is also equipotential, we have,
Veq=0
Therefore, work done in moving a positive test charge q through a distance of 1 cm is,
W=0
W = qV
Since, the equitorial plane is also equipotential, we have,
Veq=0
Therefore, work done in moving a positive test charge q through a distance of 1 cm is,
W=0
