Q.
The electric field in a region surrounding the origin is uniform and along the $x$-axis. A small circle is drawn with the centre at the origin cutting the axes at points $A,B,C,D$ having co-ordinates $(a,\ 0),\ (0,\ a),\ ( - a,\ 0),\ (0,\ - a);$ respectively as shown in figure then potential in minimum at the point
A) $A$
B) $B$
C) $C$
D) $D$
Explanation
(a) In the direction of electric field, potential decreases
