Concept explainers
To find: The magnitude of charge on each point charge.
Answer to Problem 32P
Explanation of Solution
Given:
Formula used:
The net electric field at the mid-point between the two charges is shown in the following figure:
In the figure,
The magnitude of electric fields at center due to positive charge and negative charge are as follows:
The net electric field due to two charges is as follows:
The given electric field at center is E.
Rewrite the above equation as follows:
Substitute
Calculation:
Calculate the magnitude of the charge as follows:
Substitute
Conclusion:
Therefore, the magnitude of charge on each is
