Electric Charges and Fields

Question:

Six charges each +3q are placed at the corners of a regular hexagon of each side 'a'. The electric field at the center of the hexagon is:

Options:

$\frac{\sqrt{3}}{4 x \varepsilon_0} \frac{q}{a^2}$

Zero

$\frac{\sqrt{5}}{4 x \varepsilon_0} \frac{q}{a^2}$

$\frac{3 q}{4 x \varepsilon_0 a^2}$

Correct Answer:

Zero

Explanation:

The correct answer is Option (2) → Zero

Electric field intensity at the centre of each hexagon is balanced by the opposite vertices, thereby cancelling out each other effect.

Hence, electric field intensity at the center is zero.
