| Charges are placed on the vertices of a square as shown. Let E be the electric field and V be the potential at the centre. If the charges on A and B are interchanged with those on D and C respectively, then [AIEEE 2007] |
 |
A) E remains unchanged, V changes
B) both E and V change
C) E and V remain unchanged
D) E changes, V remains unchanged
Correct Answer: D
Solution :
[d] Direction of E reverses as E is vector quantity while magnitude remains same and V remains unchanged because the net potential at the centre is the sum of potential of four changes.
