Question

Two conducting plate are inclined at an angle ${30}^{\circ }$ to each other with a point charge between them. The number of image charges are

• A. 12
• B. 11
• C. 5
• D. 6

Answer 1

The correct option is B 11

The number of image charges is given by

$N=(\frac{{360}^{\circ }}{\varphi }-1)=(\frac{{360}^{\circ }}{{30}^{\circ }}-1)=12-1=11$
