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

A

`vecE` remains unchanged, V changes

B

Both `vecE` and V change

C

`vecE` and V remains unchanged

D

`vecE` changes, V remains unchanged

Text Solution

Verified by Experts

The correct Answer is:
D
`Erarr` Vector quantity, hence direction will change.
