Five point charge (`+q` each) are placed at the five vertices of a regular hexagon of side `2a`.what is the magnitude of the net electric field at the centre of the hexazon?

Five point charges, each +q are placed on five vertices of a regular hexagon of side' l '. Find the magnitude of the resultant force on a charge –q placed at the centre of the hexagon.

Five point charges each of charge +q are placed on five vertices of a regular hexagon of side h as shown in the figure. Then

Six point charges are arrange at the vertices of a regular hexagon of side length a (shown in figure). Find the magnitude of electric field at the centre of regular hexagon.

Six point charges are arrange at the vertices of a regular hexagon of side length a (shown in figure). Find the magnitude of electric field at the centre of regular hexagon.

Six point charges are placed at the vertices of a hexagon of side 1 m as shown in figure. Net electric field at the centre of the hexagon is

Four identical point charges, each of charge q, are placed on the vertices of a regular hexagon of side a such that the net electric field at centre of hexagon is zero. If one of the charge is now removed, then the electric field at centre of hexagon is k- 4.60

Five charges, q each, are placed at the corners of a regular pentagon of side a as shown in the figure. What will be the electric field at O, the centre of the pentagon? What will be the electric field at O, fi the charge from one of the corners (Say A) is removed? What will be the electric field at O, if the charge q at A is repalced by - q?
