Chapter 4: Q22DQ (page 777)
Question: A positive point charge is placed near a very large conducting plane. A professor of physics asserted that the field caused by this configuration is the same as would be obtained by removing the plane and placing a negative point charge of equal magnitude in the mirror image position behind the initial position of the plane. Is this correct? Why or why not?
Short Answer
Answer
It is correct. In both cases electric potential is same
