Question

Six-point charges are kept at the vertices of a regular hexagon of side L and centre O, as shown in the figure. Given that $K = \frac{1}{4 {πε}_{0}} \frac{q}{L^{2}}$ , which of the following statement(s) is(are) correct?

The potential at O is zero.

The potential at all points on the line PR is same.

The electric field at O is 6K along OD.

The potential at all points on the line ST is same.

$∴ E_{res} = 6 E = 6 \frac{1}{4 {πε}_{0}} \frac{q}{L^{2}} = 6 K$

Assuming that potential is zero at $\infty$
