Question

The charges are placed at corners of a square as shown in figure. Let the electric field and electric potential at its centre be $$ \vec{E} $$ and $$ \mathrm{V} $$ respectively. If the charges at A and $$ \mathrm{B} $$ are displaced with respect to the charges at$$ \mathrm{C} $$ and $$ \mathrm{D} $$, then:

A
V changes and $$ \vec{E} $$ remains unchanged
B
Both $$ \vec{E} $$ and $$ \vee $$ remains unchanged
C
$$ \vec{E} $$ changes and $$ \vee $$ remains unchanged
D
Both $$ \vec{E} $$ and $$ \vee $$ changes
Solution
Verified by Toppr

Correct option is D. $$ \vec{E} $$ changes and $$ \vee $$ remains unchanged
(d) $$ \vec{E} $$ changes and $$ \vee $$ remains unchanged Electric field $$ \vec{E} $$ is changed while electric potential (V) remains unchanged
