Concept explainers
The potential at the fourth corner (point A).
Answer to Problem 19P
Explanation of Solution
Given:
The figure:
Potential,
Formula used:
It is known that
or
Expression for the Potential
Where, electrostatic constant,
Calculation:
Naming the points in a counter-clockwise manner and calculating potential due to each charge:
The potential at a point
It known that potential is a scalar quantity then potentials will be algebraically summed. So,
According to the question, at very large distance,
As the distance will be increase and tend to infinity, potential tend to zero. That means,
Conclusion:
Potential at point
