Question

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

• A. $\overrightarrow{E}$ and V remain unchanged
• B. $\overrightarrow{E}$ changes, V remains unchanged
• C. $\overrightarrow{E}$ remains unchanged, V changes
• D. Both $\overrightarrow{E}$ and v change

Answer 1

The correct option is B

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

Potential is a scalar quantity whereas field is not.
