Question 546: Electrostatics & Capacitance

Question

Charges are placed on the vertices of a square as shown. Let $$\overrightarrow E $$ be the electric field and $$V$$ the potential at the center. If the charges on $$A$$ and $$B$$ are interchanged with those on $$D$$ and $$C$$ respectively, then

Accepted Answer

As shown in the figure, the resultant electric fields before and after interchanging the charges will have the same magnitude, but opposite directions.
Also, the potential will be same in both cases as it is a scalar quantity.

Answer

$$\overrightarrow E $$ changes, $$V$$ remains unchanged

Answer

$$\overrightarrow E $$ remains unchanged, $$V$$ changes

Answer

both $$\overrightarrow E $$ and $$V$$ change

Answer

$$\overrightarrow E $$ and $$V$$ remain unchanged
