Answer to Problem 14.13P
The value of electric field
Explanation of Solution
Given:
The vertical current element location is
Concept Used:
Due to the change in the position of the vertical current element, there will be practically no change in the distance of P. However, this will enforce a change in the phase term which needs to be included in the overall electric field expression.
Calculation:
Consider two lines are drawn. One line is drawn from the origin to the point
The overall electric field will be obtained by using the modified result obtained in part (a) with the phase factor due to the path difference. The electric field will be,
Conclusion:
The value of electric field
